Answer:
x = 36
y = 108
z = 72
Step-by-step explanation:
Given quadrilateral is a rectangle.
Diagonals of a rectangle are congruent and bisects each other.
x° = 36° (alternate angles)
x = 36
y° = 180° - (36° + 36°) (vertical angles)
y°= 180° - 72°
y° = 108°
y = 108
z° = 36° + 36° (by exterior angle theorem)
z° = 72°
z = 72
