.Detailed Explanation

A parallelogram has 2 sets of angles that are equal to one another. That means if one angle is 54 degrees, at least one other angle (the opposite angle) must also be 54 degrees. The other two angles are each 126 degrees because 2 angles next to each other in a parallelogram are supplementary angles (add up to 180 degrees).
