Question

An angle and it's supplement are in the ratio 3:7, find the angles

Smaller angle -_________________
Larger angle -__________________

Answer 1

We already know that supplement angles are of 180°.

Let smaller angle be 3x and larger angle be 7x ..

3x + 7x = 180°

10x = 180°

x = 180/10

x = 18°

so,

3x = 3(18) = 54°

7x = 7(18) = 126°
