Answer:
A. x = 50, y = 130, z = 130
Step-by-step explanation:
50 and z are adjacent angles,
Sum of adjacent angles = 180,
50 + z = 180
z = 180 - 50
z = 130
z and x are adjacent angles,
Sum of adjacent angles = 180,
x + z = 180
130 + x = 180
x = 180 - 130
x = 50
z and y are opposite angles,
Opposite angles are equal in a parallelogram,
z = y = 130
