we are given that

ABCD is a parallelogram

so,

AB=CD

AD=BC

Calculation of x:

AB=CD


x+30=2x-10

now, we can solve for x


x=40

Calculation of y:

AD=BC


2y-10=y+10

now, we can solve for y


y=20

calculation of z:


z=x-y

we got


x=40


y=20

we can plug it


z=40-20


z=20

option-B..............Answer
