Point X and Y are on the same horizontal base as the foot of a building such that X is 96m due east of the building and Y is due west. If the angle of elevation of the top of that building from X is 30\(^o\) and that of Y is 50\(^o\), calculate the distance of Y from the base of the building.

h = 96 Tan 30\(^o\) = 55.425
P = \(\frac{55.425}{Tan60^o}\)
= 32m
