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?
Accepted Solution
A:
Answer: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
