Question

2x and 10x are two angles that are supplementary. How many degrees are each angle?

a
30° and 60°
b
60° and 120°
c
30° and 150°
d
15° and 75°

Answer 1

Hello! answer: 30 and 150

Explanation:

supplementary angles add up to 180 degrees

2 × 15 = 30

10 × 15 = 150

150 + 30 = 180 degrees therefore C is the only answer that works in this scenario

and x = 15 just a little more info
