    Use the fact that all the angles on the above the horizontal must equal 180 degrees and the angles adjacent to the parallel lines must be equal: $$ (x-3)+41+(y+8)=180\\ (x-3)=74 $$ Make sense?

    Yep. so that leaves us A or C. Now plug x=77 in first equation and solve for y.

    Can you tell me what \(m\angle1\) is? From there, you would know what \(m\angle5\) is, since they are corresponding angles.
