Go to the third pic for your answer. I got problem 4 wrong but it shows the correct answer.
We have the supplementary angles.
The sum of the measures of the two Supplementary Angles is 180°.
Therefore we have the equation:
13x - 2 + 39 = 180
13x + 37 = 180 <em>subtract 37 from both sides</em>
13x = 143 <em>divide both sides by 13</em>
<em>x = 11</em>
