Question

The ratio of two supplementary angle is 3:1. Find the measures of both angles.

Answer 1

The sum of two angle is 180 (supplementary)

given angle = 3:1

first angle =3x

2 nd angle=1x

3x+1x =180

4x =180

x = 180/ 4

x = 45

so first angle =3x x = 45

= 3×45

= 135 degree

2nd angle = 1x

=45 degree

ans

Both angles are 135 and 45
