Question

what is the answer to this problem?

Answer 1

Every two consecutive angles are supplementary

so x+115 = 180        x= 65

and x+y = 180         y = 115


you can pick the second choice 

Answer 2

X=65 or y =115, because they are supplementary meaning it must equal 180 degrees for adjacent angles. This would make it certain this is a parallelogram.
