Question

Find an angle whose supplement is 2/3 of it.

Answer 1

Answer:

108°

Step-by-step explanation:

Let the angle be x

or, 2/3 x = (180°-x)

or, 2x = 3 (180°-x)

or, 2x = 540°-3x

or, 2x + 3x = 540°

or, 5x = 540°

or, x = 108°

2/3 (108)° = 72°

The required angle is 108°

The supplementary angle is 72°
