The angle of elevation of the top of a building from the foot of the tower is 30° and the angle of elevation of the top of the tower from the foot of the building is 60°. If the tower is 50 m high, find the height of the building

Let us take DC = 50 m,

∠ACB = 30°


And,


∠ DBC = 60°;


AB= ?


In Δ DCB;






In Δ ACB






AB= 16 m
