Question

one of the two supplementary angles is 20 less than three times of the others then find them

Answer 1

Heya mate here is your answer...
Sum of supplementary angles = 180°
Therefore, 3x-20 is of that angles
Other angle = x
3x-20+x = 180°
4x-20=180°
4x = 180+20
4x =200
x= 200/4
x=50
Therefore, one angle =x=50°
Other angle =3x-20=3(50)-20
=150-20=130..

Answer 2

Heya mate here is your answer...

Sum of supplementary angles = 180°

Trefore, 3x-20 is of that angles

Other angle = x

3x-20+x = 180°

4x-20=180° he

4x = 180+20

4x =200

x= 200/4

x=50

Therefore, one angle =x=50°

Other angle =3x-20=3(50)-20

=150-20=130..
