Two poles are connected by a wire that is also connected to the ground. The first pole is 60 ft tall and the second pole is 30 ft tall. There is a distance of 90 ft between the two poles. Where should the wire be anchored to the ground (in ft, from the shorter pole) to minimize the amount of wire needed?

Hmmm. at the base of the short pole? That is 30 ft down. Anywhere else, it will be longer. maybe I am not seeing the picture here.
What i found out from working this wrong a few times, it is 30 because that is the minimum spot it would take to minimize the amount of wire needed for the project.
