46. Determine the measure of the supplementary angle to the angle shown below. m/x = 17° m/x = 90° m/x = 83° O m/x = 7° 173°

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
