Second angle (the supplement): 5x + 30

Sum of the measures of supplementary angles: 180°

Equation:

(x) + (5x+30) = 180

6x + 30 = 180

6x = 180 + 30

6x = 150

6x/6 = 150/6

**x = 25**

**ANSWER: The measure of the angle is 25°**

The supplementary angles are:

**First angle**: x =

**25°**

**Angle's supplement**: 5x + 30 = 5(25) + 30 = 125 + 30 =

**155°**

Check:

25° + 155° = 180°

180° = 180°
