Question

if the measure of an angle is twice the measure of the supplementary angle,then find its measure

Answer 1

Let angle= x

According to problem

$2x = 180 - x$

$3x = 180$

$x = 60$

The angle is 60°

Answer 2

Answer:

Step-by-step explanation:

Let the angle be = x the supplement = 180° – x

According to the question,

x = 2(180° – x)

3x = 360°

x = 120°

Hence the angle is 120°
