Let’s solve each problem step by step.
We are told these are
complementary angles. That means the two angles add up to
90 degrees.
In every diagram, one angle is given (like 30°, 32°, etc.), and we’re asked to find angle “A”. Since they’re complementary:
>
Angle A = 90° – given angle
Let’s go one by one.
---
1) Given: 30°
→ A = 90 – 30 =
60°
2) Given: 32°
→ A = 90 – 32 =
58°
3) Given: 42°
→ A = 90 – 42 =
48°
4) Given: 56°
→ A = 90 – 56 =
34°
5) Given: 27°
→ A = 90 – 27 =
63°
6) Given: 55°
→ A = 90 – 55 =
35°
7) Given: 33°
→ A = 90 – 33 =
57°
8) Given: 31°
→ A = 90 – 31 =
59°
9) Given: 51°
→ A = 90 – 51 =
39°
10) Given: 67°
→ A = 90 – 67 =
23°
11) Given: 63°
→ A = 90 – 63 =
27°
12) Given: 70°
→ A = 90 – 70 =
20°

Now let’s double-check a few to make sure we didn’t make any subtraction errors.
Check #1: 60 + 30 = 90 →
✔
Check #5: 63 + 27 = 90 →
✔
Check #10: 23 + 67 = 90 →
✔
Check #12: 20 + 70 = 90 →
✔
All look good!

3) 48
4) 34
5) 63
6) 35
7) 57
8) 59
9) 39
10) 23
11) 27
12) 20
