Question

Hello,i need help with this question:

The sum of the measures of angle M and angle R is 180⁰.

• The measure of angle M is (5x+10)⁰.

• The measure of angle R is 55⁰.

What is the value of x?

☺

Answer 1

x = 23

Explanation:

If the sum of angles is equal to 180 then we can write and equation to find the value of x

5x + 10 + 55 = 180 add like terms

5x + 65 = 180 subtract 65 from both sides

5x = 115 divide both sides by 5

x = 23
