# Supplementary angles solve for x

These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°: Notice that together they make a straight angle. But the angles don't have to be together. These two

## Using Equations To Solve Problems

Since we know that they are supplementary, we will set up our equation such that the sum of the angle measures is 180^\circ 180∘. Then we solve for x x. So, the value of x x is \textbf {9} 9. To
