Question

41. ABCD is a parallelogram. If M_ABC = 64, then?__. The diagram is not to scale.mZCDA=А AB.DСA. 64B. 116C. 126D. 74

Answer 1

Suppose that the given parallelogram is as follows:

Since opposite angles of a parallelogram are congruent, ∠CDA or ∠D must be congruent to ∠ABC or ∠B. This means that the measure of the angles must be equal.

Therefore, the measure of ∠CDA must also be 64°.
