# Angle B measures 60°. What is the measure of the angle that is complementary to angle B?

**Solution:**

Two angles are said to be complementary angles if they add up to 90 degrees. In other words, when complementary angles are put together, they form a right angle (90 degrees).

It is given that

∠B = 60°

We have to find ∠A

We can write it as

∠A + ∠B = 90°

Substituting the value of ∠B

∠A + 60° = 90°

∠A = 90° - 60°

∠A = 30°

Therefore, the measure of the angle that is complementary to angle B is 30°.

## Angle B measures 60°. What is the measure of the angle that is complementary to angle B?

**Summary:**

Angle B measures 60°. The measure of the angle that is complementary to angle B is 30°.
