A girl lets out 50 yards of kite string while flying a kite. The distance from a point on the ground directly under the kite to where the girl is standing is 30 yards. If the girl holds the string 3 feet from the ground,how high is the kite? Assume the string is tight.

a boy is flying a kite and lets out 80 meters of string.the horizontal distance along the ground from the boy to a point directly the kite is 30 meters.what is the angle of elevation?
