Question

The supplement of an angle is twice the measure of the angle. Find the measures of the angle and its supplement.

Answer 1

Answer:

Let the angle be x and supplement be 2x.

ATQ, x+2x=180

3x=180

x=180/3

x=60degree

So, angle is 60 degree and supplement be 120 degree.

Answer 2

Answer:

Let the measure of angle = x°

So its supplement angle = 2x + 60°

According to question

x + 2x + 60° = 180°

3x + 60° = 180°

3x = 180° - 60°

3x = 120°

x = 120/3

x = 40°

So the measure of angle = 40°
