Question

Draw 2 supplementary angles. One angle is x-15 degrees and one is 2x degrees. What is the value of x in degrees?

Answer 1

Explanation:

Since they are supplementary, it means the addition of both angles gives 180 degree.

`x - 15 + 2x = 180\\3x = 180 + 15\\3x = 195\\x = (195)/(3) \\x = 65`
