The supplement of an angle has a measure that is 20∘

more than twice the measure of the angle, x∘

. Which equation can be used to find the value of x?

D: (2x + 20°) + x° = 180°

Step-by-step explanation:

Supplementary angles add up to 180°, so that rules out A and C as possible answers.

Answer B has only one angle, so that is out too.

2x + 20° represents one angle, and x represents the other angle
