Dina found two angles of a parallelogram to be equal to 40 degree and 50 degree. What should we conclude about Dina's calculations and why?

The calculations are incorrect because the angles in a parallelogram are either:
The same
or complimentary (add up to 180)

Neither case is true here so the calculations are incorrect.
