Question

Angle M and angle R are supplementary.

The measure of angle R is 5 times the
measure of angle M. What is the measure
of angle R in degrees?

Answer 1

R = 150°

Explanation:

M = x

R = x*5 = 5x

`5x + x = {180}^(o) \\ 6x = {180}^(o) \\ x = \frac{ {180}^(o) }{6} \\ x = {30}^(o)`

`5x \\ 5(30) = {150}^(o)`
