Question

The measure of the supplementary angles are y and 2y the find the value of y

Answer 1

60°

Explanation:

supplementary angles are angles that sum up to give you a 180° angle

so if y and 2y are supplementary it means

y + 2y = 180°

3y=180°

Divide both sides by 3 to find y

3y÷3 = 180°÷ 3

y = 60°
