Both of the angles given are supplementary angles, meaning their values will total to 180 degrees.

In order to solve for the larger angle, you would first subtract 39 from 180.
180 - 39 = 141.

That means that the larger angle is 141 degrees. To solve for x, you set the equation equal to 141.

13x-2 =141

Then solve this equation.

First, move the 2 to the other side.

13x = 141 + 2
13x = 143

Then divide everything by 13 to isolate x.

13x/13 = 143/ 13

x = 11
