ANSWER
Angle D is 60 degrees
EXPLANATION
If quadrilateral ABCD is congruent to quadrilateral WXYZ, then the angles - in that order, are congruent,
[tex]\begin{gathered} \angle A\cong\angle W \\ \angle B\cong\angle X \\ \angle C\cong\angle Y \\ \angle D\cong\angle Z \end{gathered}[/tex]
In quadrilateral WXYZ, angle Z is 60 degrees. Therefore, in quadrilateral ABCD, the corresponding angle is angle D, thus angle D is 60°.
