So here is what we know just by looking at it.
z=10yds u=6.2yds y=38 degrees and x=90 degrees
Here is how to find W
In a right triangle there is always a right angle and two acute angles
So W is an acute angle and a right triangle adds up to 180 degrees so
here is how you figure it out 90+38=128
180-128=52
W=52
