Actually, there is
no specific problem to solve in the image you uploaded.
The image shows:
- A
learning goal: “To be able to solve word problems involving right triangles.”
- A
diagram of a right triangle formed by:
- A tree (height = `h`)
- The ground (horizontal distance from observer to tree = `x`)
- The line of sight from point A to the top of the tree (hypotenuse)
- An angle of elevation `θ` at point A
This is a
setup or illustration for trigonometry word problems — typically used to teach how to find unknown heights or distances using sine, cosine, or tangent.

✔ What this diagram is used for:
In real word problems, you might be given two of these three values and asked to find the third:
- Height of tree (`h`) — opposite side
- Distance from observer to tree (`x`) — adjacent side
- Angle of elevation (`θ`) — angle at point A
You would use the
tangent function, since:
>
tan(θ) = opposite / adjacent = h / x
So if you know `θ` and `x`, you can find `h`:
>
h = x · tan(θ)
Or if you know `h` and `θ`, you can find `x`:
>
x = h / tan(θ)
---
📌 Example Problem (if one were given):
> *You stand 20 meters away from a tree. You measure the angle of elevation to the top of the tree as 35°. How tall is the tree?*
Solution:
Use `tan(θ) = h / x`
→ `tan(35°) = h / 20`
→ `h = 20 × tan(35°) ≈ 20 × 0.7002 ≈ 14.004 meters`
✔ So the tree is approximately
14 meters tall.

❗ Conclusion:
Your image is
not a problem to solve, but rather a
visual aid to help understand how right triangles apply to real-world situations like measuring heights.
