We have three points A, B and O in a plane and point P lies a distance h above O. A is due west of O, B is due South of O and AB= 60m. The angle of elevation of P from A is 25 degrees and the angle of elevation of P from B is 33 degrees.
We have three right triangles here: AOB, AOP and BOP.
As the angle of elevation of P is 25 degrees from A, we get:
tan 25 = h/AO
=> AO = h/tan 25
As the angle of elevation of P from B is 33 degrees, we get:
tan 33 = h/OB
=> OB = h/tan 33
Now AB^2 = AO^2 + OB^2
=> 60^2 = h^2/(tan 25)^2 + h^2/(tan 33)^2
=> h^2 = 60^2*(tan 25)^2*(tan 33)^2/[(tan 25)^2 + (tan 33)^2]
=> h^2 = 516.49
h = sqrt (516.49) = 22.72 m
The height of the point P, h = 22.72 m
