The height of the kite is calculated by the equation,
        h = (sin of the angle)(s)
where h is the height and s is the length of the string.
 25 degree angle: h = (sin 25 degree)(50 ft)
     h = 21.13 ft
 45 degree angle: h = (sin 45 degrees)(50 ft)
     h = 35.35 ft
 The difference between the two numbers is 14.25 ft.
 Answer: 14.25 ft
