All you have to remember for this question is that opposite angles in a parallelogram are equal. So if you want to find another angle which is 57, just look at the angle directly opposite.
216 is the angel of g
105 degrees
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
