Question

What is the measure of X?
°

Answer 1

To find the measure of x you want to put 4x+x equaled to 180, because the measure of a straight line is 180, and 4x and x together make a straight line

Set up your equation:

4x+x=180

Add your like terms

5x=180

Divide by 5 to get x by itself

x=36

Hope this helps ;)
