Consider a tower AB 75 m high such that the angle of depression of a car at Cfrom top of the tower is 30°It is required to find the distance BC, the distance between the car and base of tower.
In right angled △ABC, we have ABBC=tan30° 75BC=13 BC=753 =751.732 =129.9 =130 m approxThus the distance between the car and base of the tower is approximately 130 m
