Click the attachment. There I have a figure of intersected lines. We call it transversal when two parallel lines are intersected by a transversal line. I can't explain it well but I hope it help.

Also, the reason why 48° is the answer because the bottom left and the top right are vertical angles. Vertical angles are congruent.

The bottom right and the top left measures 132° because they are also vertical angles, therefore, they are congruent. Also, the bottom left and the bottom right forms a linear pair, same as bottom left and top left, top right and bottom right, top right and top left, therefore, the sum of their angles measures 180°. (Just more info's.)
