Question

A figure displays two complementary nonadjacent angles. If one angle measure is 79°, what is the other angle measure?(1 point)

A. 21°

B. 11°

C. 121°

D. 101°

Answer 1

Complementary angles are two angles whose measures add up to 90°. If one angle measures 79°, you can find the measure of the other angle by subtracting 79° from 90°.

So, the calculation is:

90° - 79° = 11°

Therefore, the measure of the other angle is **11°**.

The correct answer is **B. 11°**.
