A restaurant uses a cable for the servers to slide orders down to the kitchen. The end where the servers place the order is 5 feet high. The end where the kitchen receives the order is 1 foot high. The angle of elevation from the kitchen to the servers stand is 25°. Calculate the length of the cable to the nearest hundredth of a foot.
