Right triangle with sides and height labeled, showing dimensions and relationships.

It looks like you've uploaded a geometric figure involving a trapezoid (or possibly two right triangles and a rectangle), with some labeled sides and variables. Let's analyze the diagram carefully and solve the problem step by step.

---

Understanding the Diagram

We are given a quadrilateral $ PQRS $, which appears to be a trapezoid with:

- $ PQ = 8 \text{ m} $
- $ SR = 17 \text{ m} $
- $ PS = 10 \text{ m} $
- $ QS $ is perpendicular to both $ PQ $ and $ SR $, meaning it's the height of the trapezoid.
- The height $ QS = b $
- There are two right angles at $ Q $ and $ S $, indicating that $ QS $ is perpendicular to both top and bottom bases.
- Side $ QR $ is labeled as $ c $
- Side $ PR $ is also labeled as $ c $ — this may suggest symmetry or a typo?

Wait: both $ PS $ and $ QR $ are labeled $ c $? But $ PS = 10 $ m, so if $ QR = c $, then $ c = 10 $? But $ QR $ is slanted, not vertical.

Let’s look again.

Actually, the labels seem to be:

- $ PQ = 8 $ m → top base
- $ SR = 17 $ m → bottom base
- $ PS = 10 $ m → left side
- $ QR = ? $ → right side (labeled $ c $)
- $ QS = b $ → height (vertical segment from $ Q $ to $ S $)
- $ PQ $ and $ SR $ are horizontal (since there are right angles at $ Q $ and $ S $)
- So $ PQ $ and $ SR $ are parallel, making $ PQRS $ a right trapezoid

But wait: $ PQ $ is 8 m, $ SR $ is 17 m, and $ QS $ is the height (vertical). That means the horizontal projection between $ P $ and $ S $ is different from $ Q $ to $ R $.

Let’s label the points in order: $ P \to Q \to R \to S \to P $

So:
- $ PQ = 8 $ m (top)
- $ QR = c $ (right slanted side)
- $ RS = 17 $ m (bottom)
- $ SP = 10 $ m (left slanted side)

And we have two right angles:
- At $ Q $: angle $ PQS = 90^\circ $
- At $ S $: angle $ QSR = 90^\circ $

This suggests that $ QS $ is vertical, and $ PQ $ and $ SR $ are horizontal.

Therefore, the shape is a right trapezoid with:
- Two right angles at $ Q $ and $ S $
- Parallel bases $ PQ $ and $ SR $
- Height $ QS = b $
- Non-parallel legs: $ PS $ and $ QR $

Also, note that:
- $ PQ = 8 $ m
- $ SR = 17 $ m
- $ PS = 10 $ m
- $ QS = b $ (unknown)
- $ QR = c $ (unknown)

Our goal is likely to find the missing values: $ a $, $ b $, $ c $, but the variables are labeled strangely.

Looking closely:

- Above $ PQ $: $ a $ and $ 8m $
- Below $ SR $: $ a $ and $ 17m $
- On $ QS $: $ b $ and $ b $
- On $ PS $: $ c $ and $ 10m $
- On $ QR $: $ c $

Wait — perhaps the labeling is confusing.

Let me re-label based on what’s shown:

- $ PQ = 8 $ m
- $ SR = 17 $ m
- $ PS = 10 $ m
- $ QS = b $ (height)
- $ QR = c $
- And the variable $ a $ appears above $ PQ $ and below $ SR $ — but both are already labeled with lengths.

Possibility: $ a $ might be the horizontal overhang? But that doesn’t make sense.

Alternatively, maybe $ a $ is meant to be the length of the top and bottom, but they're already labeled.

Wait — perhaps the diagram has been mislabeled.

Let’s try to reconstruct:

We have a trapezoid $ PQRS $, with:
- $ PQ $ and $ SR $ as the two parallel sides (bases)
- $ PQ = 8 $ m
- $ SR = 17 $ m
- Height $ h = b $
- Left leg $ PS = 10 $ m
- Right leg $ QR = c $
- Right angles at $ Q $ and $ S $

But wait — if there is a right angle at $ Q $, and $ PQ $ is horizontal, then $ QS $ must be vertical. Similarly, at $ S $, $ QS $ is vertical, and $ SR $ is horizontal.

So yes: $ PQ $ and $ SR $ are horizontal, $ QS $ is vertical, and $ PS $ and $ QR $ are slanted.

But now, let’s consider the horizontal projections.

Since $ PQ = 8 $ m and $ SR = 17 $ m, and $ PQ $ and $ SR $ are parallel, the difference in length is $ 17 - 8 = 9 $ m.

This extra 9 m must be distributed on the sides. But since there is a right angle at $ Q $, the horizontal component from $ Q $ to $ R $ is entirely along the base, so the overhang must be on the left side, i.e., from $ P $ to $ S $.

Let’s draw this mentally:

- Start at $ P $
- Go right 8 m to $ Q $
- Drop vertically down $ b $ m to $ S $
- Then go right 17 m to $ R $
- Then back to $ P $

Wait — that would make $ SR = 17 $ m, but then $ P $ to $ S $ is diagonal.

But $ PS = 10 $ m, and it connects $ P $ to $ S $, which is the left leg.

Now, the key is: $ QS $ is vertical, so the horizontal distance between $ P $ and $ Q $ is 8 m, and between $ S $ and $ R $ is 17 m.

But $ P $ and $ S $ are connected by a 10 m segment.

Let’s place this on coordinate plane.

Coordinate Geometry Approach

Let’s assign coordinates:

- Let $ Q = (0, 0) $
- Since $ PQ = 8 $ m and horizontal, $ P = (-8, 0) $
- Since $ QS $ is vertical and height $ b $, $ S = (0, -b) $
- Since $ SR = 17 $ m and horizontal, $ R = (17, -b) $

Now, we know:
- $ PS = 10 $ m → distance from $ P = (-8, 0) $ to $ S = (0, -b) $
- Compute $ PS $:

$$
PS^2 = (0 - (-8))^2 + (-b - 0)^2 = 8^2 + b^2 = 64 + b^2
$$

But $ PS = 10 $, so:

$$
64 + b^2 = 100 \Rightarrow b^2 = 36 \Rightarrow b = 6 \text{ m}
$$

✔ So the height $ b = 6 $ m

Now, find $ QR $: from $ Q = (0, 0) $ to $ R = (17, -6) $

$$
QR = \sqrt{(17 - 0)^2 + (-6 - 0)^2} = \sqrt{289 + 36} = \sqrt{325} = 5\sqrt{13} \approx 18.03 \text{ m}
$$

So $ c = QR = \sqrt{325} = 5\sqrt{13} $ m

Now, what about $ a $? It appears above $ PQ $ and below $ SR $. But both are labeled with lengths: $ PQ = 8 $ m, $ SR = 17 $ m.

Perhaps $ a $ is meant to be the overhang? But it’s labeled on both top and bottom.

Wait — maybe $ a $ is the horizontal projection of the left side?

But no, $ PQ $ is 8 m, $ SR $ is 17 m, so the difference is 9 m.

Since $ QS $ is vertical, and $ PQ $ is shorter than $ SR $, the horizontal extension is on the right side.

Wait — let's see:

From $ Q $ to $ R $: goes from $ x=0 $ to $ x=17 $, so horizontal component is 17 m.

From $ P $ to $ S $: from $ x=-8 $ to $ x=0 $, so only 8 m horizontally.

But the total base $ SR $ is 17 m, while $ PQ $ is 8 m, so the extra 9 m is on the right side.

That means the horizontal projection of $ QR $ includes that extra 9 m.

But $ QR $ goes from $ (0,0) $ to $ (17,-6) $, so its horizontal component is 17 m.

But $ PQ $ is only 8 m long, so the total horizontal span from $ P $ to $ R $ is:

- From $ P = (-8, 0) $ to $ R = (17, -6) $: total width = $ 17 - (-8) = 25 $ m

But $ PQ = 8 $, $ SR = 17 $, so the horizontal "overlap" is 8 m, and the rest is overhang.

But perhaps $ a $ is meant to be the horizontal leg of the triangle formed on the left?

Wait — another idea: perhaps $ a $ is the horizontal distance from $ P $ to the foot of the perpendicular, but we already have $ PQ $ and $ QS $.

Alternatively, maybe $ a $ is the projection of $ PS $?

But $ PS $ goes from $ (-8, 0) $ to $ (0, -6) $, so horizontal component = 8 m, vertical = 6 m.

But $ PQ = 8 $ m, so $ a = 8 $? But it's labeled on both top and bottom.

Wait — perhaps the labels are misleading.

Looking back: the diagram shows:

- Above $ PQ $: $ a $ and $ 8m $
- Below $ SR $: $ a $ and $ 17m $

But $ PQ = 8 $ m, $ SR = 17 $ m — so unless $ a $ is both 8 and 17, that can't be.

Unless $ a $ is not the length, but something else.

Wait — perhaps $ a $ is the horizontal segment from $ P $ to $ Q $, and also from $ S $ to $ R $? But those are different.

No — $ PQ = 8 $, $ SR = 17 $

Alternatively, maybe $ a $ is the same length on both ends? But it's not.

Another possibility: perhaps the diagram is showing that $ a $ is the horizontal overhang on the left and right?

But that doesn’t make sense.

Wait — here's a better idea:

Maybe $ a $ is the horizontal component of the non-parallel sides?

But we already solved for $ b $ and $ c $.

Let’s summarize what we have:

- $ b = 6 $ m ✔
- $ c = \sqrt{17^2 + 6^2} = \sqrt{289 + 36} = \sqrt{325} = 5\sqrt{13} $ m ≈ 18.03 m ✔
- $ a $: still unclear

But wait — perhaps $ a $ is the length of the top and bottom? But they’re labeled separately.

Wait — look at the labels:

- Above $ PQ $: $ a $ and $ 8m $
- Below $ SR $: $ a $ and $ 17m $

This suggests that $ a $ is being used for both, but they are different lengths.

That can't be unless it's a typo.

Alternatively, perhaps $ a $ is the horizontal distance from $ P $ to the point directly above $ S $, but that's just 8 m.

Wait — another thought: perhaps $ a $ is the projection of $ PS $?

But $ PS $ has horizontal component 8 m (from $ x=-8 $ to $ x=0 $), vertical 6 m.

But $ PQ = 8 $ m, so maybe $ a = 8 $ m?

Similarly, on the right, $ QR $ has horizontal component 17 m, but $ SR = 17 $ m.

But $ a $ is written under both, so perhaps $ a $ is meant to be the horizontal base of the left triangle?

But the left triangle is $ PQS $, with base $ PQ = 8 $ m.

Wait — perhaps the diagram intends $ a $ to be the horizontal leg of the left right triangle, which is $ PQ = 8 $ m, and $ b = 6 $ m.

Similarly, on the right, the triangle is $ QSR $, with base $ SR = 17 $ m, height $ b = 6 $ m.

But then $ a $ is labeled on both, so maybe $ a $ is not the length, but the variable name for the top and bottom?

But that doesn't help.

Alternatively, perhaps the task is to find $ a $, $ b $, and $ c $, and the labels are:

- $ a $: length of $ PQ $ = 8 m
- $ a $: length of $ SR $ = 17 m → contradiction

So that can't be.

Unless $ a $ is not the length, but the horizontal overhang?

Wait — maybe the diagram has a typo.

Another possibility: perhaps $ a $ is the horizontal projection of $ PS $, which is 8 m, and $ b $ is the height, 6 m, and $ c $ is the length of $ QR $, which is $ \sqrt{17^2 + 6^2} = \sqrt{325} $

But the label $ a $ appears on both top and bottom — maybe it's a mistake.

Wait — perhaps $ a $ is the horizontal segment from $ P $ to $ Q $, and also from $ S $ to $ R $? But they are different.

Unless the figure is symmetric, but it's not.

Given all this, the most reasonable interpretation is:

- We are to find $ b $ (height) and $ c $ (length of $ QR $)
- $ a $ is either a typo or refers to the horizontal segments, but since $ PQ = 8 $, $ SR = 17 $, $ a $ cannot be both.

But perhaps $ a $ is the horizontal leg of the left triangle, so $ a = 8 $ m, and $ b = 6 $ m, and $ c = \sqrt{17^2 + 6^2} = \sqrt{325} $

Alternatively, maybe $ a $ is the overhang on the right side?

The total horizontal span is from $ x = -8 $ to $ x = 17 $, so 25 m.

But $ PQ = 8 $, $ SR = 17 $, so the overhang on the right is $ 17 - 8 = 9 $ m?

But $ a $ is labeled on both ends.

Wait — perhaps $ a $ is the horizontal component of the left side? But it's 8 m.

I think the best conclusion is:

- $ b = 6 $ m (height)
- $ c = \sqrt{17^2 + 6^2} = \sqrt{289 + 36} = \sqrt{325} = 5\sqrt{13} $ m
- $ a $: likely a typo or mislabel — perhaps it should be $ a = 8 $ m for $ PQ $, and $ a $ is not the same as $ SR $

But since $ a $ is labeled on both, and they are different, probably $ a $ is not a variable for length.

Alternatively, maybe $ a $ is the horizontal leg of the right triangle on the left, so $ a = 8 $ m

Then $ b = 6 $ m

And $ c $ is the hypotenuse of the right triangle on the right: base 17 m, height 6 m, so $ c = \sqrt{17^2 + 6^2} = \sqrt{325} $

But the left side $ PS = 10 $ m, which matches $ \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10 $, correct.

So the solution is:

- $ a = 8 $ m (horizontal leg on left)
- $ b = 6 $ m (height)
- $ c = \sqrt{17^2 + 6^2} = \sqrt{325} = 5\sqrt{13} $ m

Even though $ a $ is also labeled under $ SR $, which is 17 m, perhaps it's a labeling error.

Alternatively, maybe $ a $ is meant to be the horizontal overhang on the right, but that would be $ 17 - 8 = 9 $ m, but then why label it on both?

I think the most plausible explanation is that:

- $ a $ is the length of $ PQ $ = 8 m
- $ b $ is the height = 6 m
- $ c $ is the length of $ QR $ = $ \sqrt{17^2 + 6^2} = \sqrt{325} = 5\sqrt{13} $ m

And the labeling of $ a $ under $ SR $ is a mistake — it should be $ d $ or something.

Alternatively, perhaps $ a $ is the horizontal distance from $ P $ to $ S $, but that's not straight.

Given the data, I'll assume the task is to find $ b $ and $ c $, and $ a $ is given as 8 m.

✔ Final Answer:

- $ a = 8 $ m (given, length of $ PQ $)
- $ b = 6 $ m (height, calculated from $ PS = 10 $ m and horizontal leg 8 m)
- $ c = \sqrt{17^2 + 6^2} = \sqrt{289 + 36} = \sqrt{325} = 5\sqrt{13} $ m ≈ 18.03 m

---

✔ Step-by-step Solution:

1. Place the trapezoid on coordinate plane:
- $ Q = (0, 0) $
- $ P = (-8, 0) $ (since $ PQ = 8 $ m)
- $ S = (0, -b) $
- $ R = (17, -b) $

2. Use $ PS = 10 $ m:
- Distance from $ P(-8, 0) $ to $ S(0, -b) $:
$$
\sqrt{(0 + 8)^2 + (-b - 0)^2} = \sqrt{64 + b^2} = 10
$$
$$
64 + b^2 = 100 \Rightarrow b^2 = 36 \Rightarrow b = 6 \text{ m}
$$

3. Find $ QR $:
- $ Q(0,0) $ to $ R(17, -6) $
- $ QR = \sqrt{(17)^2 + (-6)^2} = \sqrt{289 + 36} = \sqrt{325} = 5\sqrt{13} $ m

4. Thus:
- $ a = 8 $ m (top base)
- $ b = 6 $ m (height)
- $ c = 5\sqrt{13} $ m (right slanted side)

🟩 Final Answer:

$$
\boxed{
a = 8\,\text{m}, \quad
b = 6\,\text{m}, \quad
c = 5\sqrt{13}\,\text{m} \approx 18.03\,\text{m}
}
$$
