Answer:
117 degrees
Step-by-step explanation:
if de is congruent to df then the angles def and dfe are also congruent. a triangle adds to 180. So you can do 180-(63+63) to fing edf. You get 54 for angle edf. angle dfe is 117 through linear pair and cbf is 63 through corresponding angles. abf is 117 through linear pair and c is now 117 through corresponding angles
