Question

A lamppost casts a shadow of a man who is standing 10 feet away from the lamppost. The shadow is 5 feet long. The angle of elevation from the tip of the shadow to the lamp is 50. To the nearest foot, the lamp post is _____ feet tall.

Answer 1

It may help to draw out this scenario. If you have a man 10 ft. away and the shadow that is cast from him is another 5 ft. away. The total distance between the tip of the shadow and the lamp post would be 15 ft. Are you familiar with the tangent function?

Answer 2

Tan(Angle) = Opposite/Adjacent
In other words...
Tan(50) = x/15
15*(Tan(50)) = x
