Question
A surveyor standing at a point X sites a pole Y due east of him and a tower X of a building on a bearing of 046 degrees, after walking to a point W, a distance of 180m on the south east direction, he observes a bearing of Z and Y to be 337 degrees and 050 degrees respectively . Calculate to the nearest meter line XY

I think your diagram is in error, since W is SE of X.
In triangle XYW, we have
X=45°, Y=40°, W=72°
So now we have
XY/sin72° = 180/sin40°
XY = 266.32
