Answer given in book x= 28 y= 112 z=28
plz solve it

Answer:
Step - 1 : State the properties.
 In a parallelogram ABCD , The opposite angles are equal.⇒∠A = ∠C,∠B = ∠D.
The consecutive angles of parallelogram is supplementary.⇒∠A + ∠B = 180∘,∠C + ∠D = 180∘.
Step - 2 : Solve for (i).
Here 100∘ + z=180∘[∵Adjacent angles of a parallelogram].
⇒z = 80∘.
Opposite angles are same.⇒x = z = 80∘,y = 100∘.
Step - 3 : Solve for (ii).
Here x∘ + 50circ = 180∘. [Adjacent angle]
⇒x∘ = 130∘.
x and y are opposite angles.So x = y = 130∘.
x and z will corresponding angles, z = 130∘.
Step - 4 : Solve for (iii).
Here as x and 90∘ vertical opposite angles,So x = 90∘.
As 90∘,30∘,y are in a triangle.⇒90∘+30∘+y = 180∘.
⇒y = 60∘.
y and z are alternate angles .
⇒y = z = 60∘.
Step - 5 : Solve for (iv).
Here z and 80∘ are corresponding angles.So z = 80∘.
