Question

The measure od an angle is twice the measure of its supplementry angle .find its measure

Answer 1

Answer:

120 degree

Step-by-step explanation:

Let the supplementary angle be x

Therefore, the angle will be 2x

From the formula Supplementary angle = 180- the angle itself

We van day that, the angle + supplementary angle= 180 degree

Substituting the value of angle and supplementary angle we get

x +2x =180

3x =180

x=180/3

x=60

Angle =2x

=2*60=120 degree

Answer 2

Answer:

120

Step-by-step explanation:

Let the angle be = x the supplementary angle be 1 80 – x

According to the question,

x = 2(180 – x)

3x = 360

x = 120

Hence the angle is 120
