258 ft 13. A person flying a kite originally lets out 232 feet of line. At this point the person observes an angle to the kite of 48°. The person then lets out an additional line for a total of 258 feet. At this point the person observes an angle of 53°. If the kite rise vertically between the two points in the time as shown, determine, to the nearest foot, how much higher the kite is as point C than at point B. B. 232 ft 53° 48° A
