Step-by-step explanation:

Answer. In this solution, the one supplement angle is taken by X and twice of supplement angle is 2X. So that it remains two supplement that is measured by angle at 180 degree and then consider it as X x+2x=180°

, 3x=180°,

3x=180°, x=180÷3=60°,

3x=180°, x=180÷3=60°, 2×60=120°
