Answer:
1. They are supplementary angles
2. They are complimentary angles
3. 90 - 45 = 45°
4. 90 - 82 = 8°
5. 90 - 23 = 67°
6. 180 - 173 = 7°
7. 180 - 75 = 105°
8. 180 - 92 = 88°
9. Angle 1 = 137° because 180 - 43 = 137 (they are supplementary)
Angle 2 = 43° because 180 - 137 = 43 (they are supplementary)
Angle 3 = 137° because 180 - 43 = 137 (they are supplementary)
10. a) Vertical: e and c
b) Complimentary: ∠c and ∠b
c) Supplementary: ∠c and ∠d
d) All adjacent: ∠e ∠a and ∠b
e) All value of angles if c = 30°:
∠a = 90°
∠b = 60° (90 - 30)
∠c = 30°
∠d = 150° (180 - 30)
∠e = 30° (vertical angles)
