Let "a" represent the angle. Then its complement is (90-a). The complement is 39° more than the angle, so we have
  (90-a) - a = 39
  51 = 2a
  25.5 = a

The measure of the angle is 25.5°; its complement is 64.5°.

Answer:

25.5⁰

Step-by-step explanation:

Angle = x

Complement = 90 - x

Given :

90 - x = x + 39

2x = 51

x = 25.5⁰
