Question

The measure of an angle is 39°. What is the measure of its complementary angle?

Answer 1

51 degrees

Explanation:

Complementary angles are two angles whose sum is (90degrees). If one is given an angle measure and needs to find its complementary angle, then all one has to do is subtract the given angle measure from (90degrees).

90 - 39 = 51

Answer 2

• 51°

Explanation:

• Complementary angles add to 90°.

If one of them is 39°, then the other is:

• 90° - 39° = 51°
