cables of a suspension bridge in the shape of a parabola, as shown in the figure. The towers supporting the cable are 200 feet apart and 20 feet high. If the cables touch the road surface midway between the towers, what is the height of the cable at a point 50 feet from the center of the bridge? 20 ft 200 ft The cable is feet from the road surface at a point 50 feet from the center of the bridge. (Simplify your answer. Type an exact answer, using radicals as needed.)
