Question

The larger of two supplementary angles exceeds the
smaller by 20 degrees. Find the angles.​

Answer 1

Answer:

The angles are 140° and 40°.

Answer 2

Answer:

Let the smaller angle be x

let the larger angle be x + 20

A.T.Q

The sum of supplementary angle is 180

x + x + 20 = 180

2x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80

The smaller angle is 80

The larger angle is 80 + 20 = 100
