and the angle of

elevation of the top of the tower from the foot of the building is 60°

. If the tower is 70M high,

find the height of the building.​

Answer 1

Answer:

The angle of elevation of the top of the tower from the foot of the building = 60 deg.

It the tower is 60 m high, the building is at a distance of 60 cot 60 = 34.64101615 m from the tower.

The height of the building = 34.64101615 tan 30 = 20 m. Answer
