Answer:
DCA = 49*
Step-by-step explanation:
This is because of the fact that we have 2 pairs of vertical angles. Vertical angles are 2 angles made by 2 intersecting lines. They are also equivalent to each other. So that means that Angle BCA = BEC + AEB. Now we know that it is the same for Angle DCA.
