Two angles are supplementary. The first angle measures 60°. What's the measurement of the second angle?

Question

Question 14 options:

A)

90°

B)

120°

C)

180°

D)

30°

Answer 1

Supplementary angles are two angles that add up to 180°. If the first angle measures 60°, you can find the second angle by subtracting 60° from 180°:

180° - 60° = 120°

Therefore, the measurement of the second angle is 120°.

The correct option is:

B) 120°
