We know that adjacent angles of a parallelogram are supplementary.
Also, it is given that the two angles are equal.
Let the angles be x and y.
Therefore x+y=180.
                               But, x=y
Therefore x+x=180
2x=180
Therefore x=90


Therefor answer = 90


I think that should help.

Sum of angles of a quadrilateral is 360 so from question we get all angles in the parallelogram is equal
so 4x = 360
so x = 90
