#sine (18) = (side opposite to angle given) /100#

#Side = 100 * sine (18) #
which is the value of the distance from the ground to the kite

Explanation:

When illustrating you should end up with a drawing of a right angled triangle, with the hypotenuse being the 100 foot long string, the angle of 18 degrees being between it and the ground.

In this case you simply use the sine identity and make the value of side opposite to the given angle, in this case the distance from the ground to the kite, the subject of the formula as shown above.
