Explanation:
Any rhombus is a parallelogram, but not the other way around.
For any parallelogram, the opposite angles are congruent.
-8y-8 = 88
-8y = 88+8
-8y = 96
y = 96/(-8)
y = -12
Also, for any parallelogram, the adjacent angles are supplementary (meaning they add to 180).
(-3x+8) + (88) = 180
-3x+96 = 180
-3x = 180-96
-3x = 84
x = 84/(-3)
x = -28
And we can also say,
88 + (-9z-7) = 180
-9z+81 = 180
-9z = 180-81
-9z = 99
z = 99/(-9)
z = -11
