Question

A person observed the angle of elevation of the top of a electrical pole as 30°. he walked 5 meters towards the foot of the tower along level ground and found the angle of elevation of the top of the pole as 60°. draw the suitable diagram

Answer 1

now solve using the thing given

Answer 2

We will assume h be the height of the building.

ΔABC tan 60° = AB/BC

√3 = h/x

x = h/√3

And in the Right Angle ABD,

tan 30° = AB/BD

= 1/√3 = h/ x + 50

= h/√3 + 50 = √3h

h = 25√3m
