Question

The measure of an angle is twice the measure of its supplement angle find its measure

Answer 1

Answer:

Supplement = 180 - angle measure. Supplementary angles add to 180 degrees.

So of the measure of the angle is x, the measure of its supplement is 2x.

x + 2x = 180

3x = 180

x = 60

Angle = 60, supplement = 120.

Answer 2

Answer:

Step-by-step explanation:

Supplementary angles sum up to 180°.

Supplement = 180 - angle measure.

So, if the measure of the angle is x, the measure of its supplement is 2x.

.°. x + 2x = 180°

3x = 180°

x = 60°

Angle = 60* and it's supplement = 120°.
