Question

2 supplementary angles r in the ratio 2:7 find the angle (method)

Answer 1

$\mathfrak{\huge{Answer:}}$

Given:

Ratio of supplementary angles = 2 : 7

The supplementary angles have their sum equal to 180°

Now,

Let the angles be = 2x and 7x

Doing the same,

=》 2x + 7x = 180°

=》 9x = 180°

=》 x = 20°

2x = 40°

7x = 140°
