A six foot tall man stands in the shadow of a 18 foot tall telephone pole. If the man is standing 3 feet from the base of the telephone pole, what is the length of the telephone's shadow?

Distance from pole to man is 3 ft

Distance from pole to tip of shadow is x

Distance from man to tip of shadow is x/3 (by proportion)
