Hey!!!
Here's your answer:
<A=7x+40
<B=60 degree
7x+40+60=180( sum of angle in straight line)
or,7x+100=180
or,7x=180-100
or,7x=80
or,X=80/7
X=11.42
Now,
Replacing value,
<A=7x+40
=7*11.42+40
=79.94+40
= 119.94 degree
<B=60 degree
<C=<A[ being vertically opposite angles]
<C=119.94 degree
<D=<B[being vertically opposite angles]
<D=60 degree
<W=<A[ being corresponding angles]
<W=119.94 degree
<X=<B[being corresponding angles]
<X=60 degree
<Y=<W[being vertically opposite angles]
<Y=119.94 degree
<Z=<X[being vertically opposite angles]
<Z=60 degree.
Hope it will help you
Good luck on your assignment
