The two angles given are vertically opposite angles, which makes them equal. This means that we can solve for x:
7x + 8 = 5x + 32
- 5x
2x + 8 = 32
- 8
2x = 24
÷ 2
x = 12
So now that we know what x is, we can substitute it into 7x + 8, which would be (7 × 12) + 8 = 84 + 8 = 92°
So your answer is B. 92°. I hope this helps!
