Question

The meaaure of angle is 20degree more than three times its supplyment find the measure of the angle

Answer 1

Heya..

Supplementary angles are those whose sum is 180°

Let the angles be x and 3x+20

x + 3x + 20 = 180
4x + 20 = 180
4x = 180-20
4x = 160
x = 160/4
x = 40

Angles are
x = 40°
3x+20 = 3*40+20
= 120+20
= 140°

Answer 2

heya.....

let angles be x, 3x + 20
x + 3x + 20 = 180
4x = 160
x = 160 ÷ 4

x = 40
3x + 20 = 140
