Two posts, one 12 feet high and the other 28 feet high, stand 30 feet apart. They are to be stayed by two wires, attached to a single stake, running from the ground level to the top of each post. The total length of the wire is given by L = Jx2 + 144+ Vx² – 60x + 1684 where x is the distance between the stake and the shorter post. Find the distance x that minimizes the total length of the wire.
