Default Calculus Pole/Wire question?

Two vertical poles 15 & 20 ft above the ground are to be reinforced by a wire connected to the top of the poles and tied to a stake driven in the ground between the poles. Locate the stake with respect to one of the poles if the poles are 21 ft apart, and a minimum amount of the wire is to be used.
