Question

Find the measure of an angle whose supplement measures two times its measure

Answer 1

first angle = 60

second angle = 120

Explanation:

Let the first angle x

Let the second angle = 2x

x + 2x = 180 Supplementary angles = 180 degrees

3x = 180 Divide by 3

3x/3 = 180/3

x = 60

2x = 120
