Answer:

x +3x = 180
x = 45 . . . . . . . choice C
3x = 135 . . . . . choice F

Step-by-step explanation:

Let x represent the measure of the original angle in degrees. Three times its measure is 3x. That will be the supplement if the sum of the two angles is 180°.

x + 3x = 180 . . . . . . . . . equation for finding the angle

x = 180/4 = 45 . . . . . . divide both sides by 4

3x = 3(45) = 135

The first angle is 45°. The second angle is 135°.
