an angle which is equal to is complement
Let the angle be x.
Then its complement will be (90° - x)
According to the question
x = 90° - x
⇒ x + x = 90°
⇒ 2x = 90°
⇒ x = 90°/2 = 45°
Hence, required angle is 45°
Find the measure of an angle which is
(i) equal to its complement,
(ii) equal to its supplement.
