ABC congruent to XYZ means:
angle A is congruent to angle X
angle B is congruent to angle Y
angle C is congruent to angle Z
angle A is congruent to angle X, so angle A is equal to 48 degrees.
angle B = 180 - m<C - m<A = 180 - 62 - 48 = 70
angle B is congruent to angle Y, so m<Y = 70
angle Z is congruent to angle C, so m<Z = 62
c. m<A = 48
