Question

Find the measure of an angle which is 2/3 of its suplement​

Answer 1

Answer:

180 * 2/3 = 120

Step-by-step explanation:

Magnitude of a supplementary angle is 180 degree so we want to multiply 180 with 2/3

Answer 2

Let the measure of an angle=x°

Then, the measure of its supplement=(180-x)°

A/q X=2/3(180-x)°

3x=2(180-x)°

3x=360-2x

3x+2x=360°

5x=360°

x=360/5

x=72°

The measure of an angle=72°
