Kari is flying a kite. she releases 50 feet of string. what is the approximate difference in the height of the kite when the string makes a 25 degree angle with the ground and when the string makes a 45 degree angle with the ground? round to the nearest tenth.

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.
  14.25 ft

It should be c i think.
