The triangle sum theorem states that the sum of measure of all the interior angles in a triangle equals 180; in this case, the fact that both lines are parallel has little significance to this particular problem.

 

\(m\angle 7+63+61=180\) This is based on the triangle sum theorem mentioned above. Now, solve for the remaining unknown angle.
\(m\angle 7+124=180\)  
\(m\angle 7=56^{\circ}\)
