Question

Angle b measures 60°. what is the measure of angle that is complementary to angle B?

Answer 1

Since a complementary angle is two angles that equal 90 degrees the compliment of angle B would be 30 degrees since 60+30 = 90.

Answer 2

Solutions

Complementary angle are two angles whose sum is 90°. We know that Angle b measures 60°.

60° + (X) = 90°

90° - 60° = (X)

90° - 60° = 30°

(X) = 30°

30° complementary to Angle B
