Zx=20 becoz x=90 and z=45 so,y=45 :. it is a isocelesΔ and the two sides of it are always same.

In this triangle
angle y=180-x+z
so y= 45
and since two angles are same so their sides must have to be same by isosceles property
so zx=20
or by tan 45=20/q    here q is length of zx
so 1=20/q
so 20=q
20=zx
