The measure of an angle is 12° less than twice the measure of its supplement. what is the measure of the angle?
64°
34°
28°
116°

The measurement of the required angle = 116°

Step-by-step explanation:

Let the measure of its supplement = x

The measurement of the required angle = 2x - 12

x + 2x -12 = 180

3x - 12 = 180

3x = 180 + 12

3x = 192

x = 192/3

x = 64°

The measurement of the required angle = 2 * 64 - 12 = 128 - 12 = 116°
