Problem: Identify the angle of the complementary angle.
#### Definition of Complementary Angles:
Two angles are
complementary if the sum of their measures is
90°. If one angle is \( x \), then its complementary angle is \( 90^\circ - x \).
#### Solution:
We will solve each part step by step:
---
Part 1:
- Given angle: \( 36^\circ \)
- Complementary angle: \( 90^\circ - 36^\circ = 54^\circ \)
Answer for Part 1: \( \boxed{54^\circ} \)
---
Part 2:
- Given angle: \( 40^\circ \)
- Complementary angle: \( 90^\circ - 40^\circ = 50^\circ \)
Answer for Part 2: \( \boxed{50^\circ} \)
---
Part 3:
- Given angle: \( 25^\circ \)
- Complementary angle: \( 90^\circ - 25^\circ = 65^\circ \)
Answer for Part 3: \( \boxed{65^\circ} \)
---
Part 4:
- Given angle: \( 70^\circ \)
- Complementary angle: \( 90^\circ - 70^\circ = 20^\circ \)
Answer for Part 4: \( \boxed{20^\circ} \)
---
Part 5:
- Given angle: \( 75^\circ \)
- Complementary angle: \( 90^\circ - 75^\circ = 15^\circ \)
Answer for Part 5: \( \boxed{15^\circ} \)
---
Part 6:
- Given angle: \( 85^\circ \)
- Complementary angle: \( 90^\circ - 85^\circ = 5^\circ \)
Answer for Part 6: \( \boxed{5^\circ} \)
---
Part 7:
- Given angle: \( 20^\circ \)
- Complementary angle: \( 90^\circ - 20^\circ = 70^\circ \)
Answer for Part 7: \( \boxed{70^\circ} \)
---
Part 8:
- Given angle: \( 50^\circ \)
- Complementary angle: \( 90^\circ - 50^\circ = 40^\circ \)
Answer for Part 8: \( \boxed{40^\circ} \)
---
Final Answers:
1. \( \boxed{54^\circ} \)
2. \( \boxed{50^\circ} \)
3. \( \boxed{65^\circ} \)
4. \( \boxed{20^\circ} \)
5. \( \boxed{15^\circ} \)
6. \( \boxed{5^\circ} \)
7. \( \boxed{70^\circ} \)
8. \( \boxed{40^\circ} \)
