Answer:

Main concept to be known,

1) Opposite angles are equal in parallelogram

2) Adjacent angles are equal to 180°.

Step-by-step explanation:

In figure (i)

x = 80°

y = 100°

z = 80°

In figure (ii)

x = 130°

y = 130°

z = 130°

In figure (iii)

x = 90°

y = 60°

z = 60°

In figure (iv)

x = 100°

y = 80°

z = 80°

In figure (v)

x = 28°

y = 112°

z = 28°
