A boy flying a kite lets out 300 feet of string which makes an angle of 38° with the ground.
Assuming that the string is straight, how high above the ground is the kite? Round to the nearest foot
~~~~~~~~~~~~~~~~~~~~~

In this problem, you have a right triangle, its hypotenuse of 300 ft long
and the angle of 38°, opposite to the height (=altitude) h, which is an unknown.


So, use the definition of the sine

    sin(38°) = h%2F300,


and find the height

    h = sin%2838%5Eo%29%2A300 = 0.61566147532%2A300 = 184.7  feet  (rounded).

At this point, the solution is complete.
