Answer:

Step-by-step explanation:

51 and y are equal if you are given a rhombus.

y and x are supplementary

x + y = 180

y = 51

x + 51 = 180            Subtract 51 from both sides

x = 180  - 51

x = 129

z = x

x = 129
Y is the opposite from the known angle, so it’s also 51 degrees.

The total of the parallelogram is 180 degrees, so 180-2x51=78 for x and z together
So x=z=78/2=39
