Answer:
135°
Step-by-step explanation:
Angle 8 and the one marked 45° are a linear pair, so are supplementary.
angle 8 = 180° -45°
angle 8 = 135°
It would be 68 students more because if you subtract 17 from 85 you would get 68
The answer is -9/7. (Or: -1 2/7)
You can simply add the numerators: -5+-4, which equals -9. Keep the denominators.
