Answer: 
Step-by-step explanation:

88 can be rewritten as 8 x 10 and 8 can be rewritten as
making a 2 come out of the root.

10 can be rewritten as 2 x 5.

2*2 can also be rewritten as
making a 2 come out of the root.

We can't keep simplifying the root.
Angle W:
180 = 90 + 57 + W
180 = 147 + W
W = 33 degrees
Using trigonometry functions to find the side lengths. (SOH CAH TOA)
Side XZ:
cos(57) = XZ / 18
XZ = cos(57) x 18
XZ = 9.8 units
Side XW:
sin(57) = XW / 18
XW = sin(57) x 18
XW = 15.1 units
Hope this helps!! :)
