Answer:
8.) ∠R = C.) 145°
9.) ∠S = B.) 35°
10.) ∠T = A.) 145°
Step-by-step explanation:
[there's an error in question #8's answer choices]
- ∠R and ∠T have the same angle measure.
- ∠S and the 35° angle have the same angle measure.
Evidence:
║A straight angle is 180°, and we are given 35° for the first angle. By ║subtracting 35° from 180°, we get our answer for ∠R, which is 145°.
║Opposite angles are always equal in measurement. That means that ∠S is ║35°, and ∠T is 145°.
