Question

The sum of the measures of angle M and angle R is 180° .

· The measure of angle M is (5x+10°)
· The measure of angle R is 45°.

What is the value of x?

PLEASE EXPLAIN HOW TO DO IT!​

Answer 1

x =25

Explanation:

<M + <R = 180

We know M = 5x+10 R = 45

Substituting these values in

5x+10 + 45 = 180

Combine like terms

5x+55 = 180

Subtract 55 from each side

5x+55-55 = 180 -55

5x = 125

Divide each side by 5

5x/5 = 125/5

x = 25
