we are given that

ABCD is a parallelogram

so,

AB=CD

AD=BC

Calculation of x:

AB=CD

[tex] x+30=2x-10 [/tex]

now, we can solve for x

[tex] x=40 [/tex]

Calculation of y:

AD=BC

[tex] 2y-10=y+10 [/tex]

now, we can solve for y

[tex] y=20 [/tex]

calculation of z:

[tex] z=x-y [/tex]

we got

[tex] x=40 [/tex]

[tex] y=20 [/tex]

we can plug it

[tex] z=40-20 [/tex]

[tex] z=20 [/tex]
