The measure of an angle is 63.6°. what is the measure of a complementary angle?

Complementary angles add up to 90°.

You are given one angle that is 63.6°.

Let's make the other angle "x".

63.6 + x = 90

To find x, all you have to do is subtract the other angle (63.6) from 90.

90 - 63.6 = 26.4

x = 26.4

The measure of the complementary angle is 26.4°.
