Mathematical diagram showing angles of elevation to the base and top of a tower on a hill from an observer.

Mathematical diagram showing angles of elevation to the base and top of a tower on a hill from an observer.
Pro

The angle of elevation to the bottom of a transmission tower on a hall from an observer 1.8km away from the base of the hill is 5degrees. The angle of elevation from the top of the tower from the observer is 6.8degrees. If the distance from the observer to the base of the hill is 1.8km, find the height of the tower to the nearest metre. See more
