Question 483431
You have a kite with 12 ft of string. The angle to your kite is 60 degrees from  the ground where you are. How high is the kite, perpendicular to where the kite is in the sky?

sine 60 =  opposite distance (height) / 12 feet (hypotenuse).
10.39 = distance from the ground to the kite.
We can also check this by using the fact that the distance from the ground would be the side opposite the 60 degree angle in a 30 60 90 triangle. The hypotenuse is given as 12, so the formula will be 12 * {{{sqrt(3)}}}/2. 
This does confirm to 10.39 feet.
