Question

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

Answer 1

the answer is 30

Explanation:

Answer 2

30°

Explanation:

When two angles add to 90°, we say they "Complement" each other.

Hence,

Angle B + Angle A = 90°

60° + Angle A = 90°

Angle A = 90° - 60° (Subtracting both sides by 60°)

Angle A = 30°
