Question

One supplementary angle is 20 degree more than the other. Find the two angels

Answer 1

Answer:

Angles are 80° and 100°

Step-by-step explanation:

x + 20° = 180° - x

2x = 160°

x = 80°

Answer 2

Step-by-step explanation:

ATQ,

1st angle=x

2nd angle=x+13

as both the angles are supplementary then,

x+x+20=180

2x+20=180

2x=180-20=160

x=160/2

=80°

one angle is 80°

Other angle is 20 more so,

80°+20°=100°

The other angle is 100°
