Question

(a) An angle measures 51°. What is the measure of its complement?

(b) An angle measures 113°. What is the measure of its supplement?

Answer 1

Explanation:

For a

Let the another angle be x then

x + 51° = 90° {being complementary angles }

x = 90° - 51°

x = 39°

For b

Let the another angle be x then

x + 113° = 180° {being supplementary angles }

x = 180° - 113°

x = 67°
