Two poles are connected by a wire that is also connected to the ground. The first pole is 20 ft tall and the second pole is 10 ft tall. There is a distance of 30 ft between the two poles. Where should the wire be anchored to the ground to minimize the amount of wire needed? Hint: Use similar triangles. L1=(x^2+10^2 ) L2=((30-x)^2)+20^2 )
