The measure ot angle angle WZY i s​ (a)   The measure of angle ZYX is ​ (b)   The measure of angle WXY is ​ (c)  

• 75

• 24

• 28

• 105

Answer explanation

Adjacent angles of a parallelogram are supplementary so angle Z and x are 75 degrees. THis is true because the sum of 75 amd 105 is 180 degrees. WE also know that the opposite angles of a parallelogram are congruent to angle y has the same measure as angle w which is 105 degrees
