$74^{\circ}, 28^{\circ}, 78^{\circ}$

Work Step by Step

1. These angels are marked as congruent, so they have the same measure $\angle X= \angle T= 74^{\circ}$ $\angle Y= \angle V= 28^{\circ}$ 2. To find third number we apply the rule that sum of angles of a triangle is 180 degrees $\angle Z= \angle W= 180^{\circ}-74^{\circ}-28^{\circ}=78^{\circ}$
