The cable for the central span of a suspension bridge takes the shape of a parabola. If the towers are 900 meters apart and the cables are attached to them at points 500 meters above the floor of the bridge. How long must the verticals strut be that is 200 meters from the tower? (The cable touches the bridge bottom at the midpoint)
