Suppose that Mark is flying a kite with the string tied to his glasses (so that it’s easy to measure the angle of elevation, of course). Mark’s eyes are 6 feet above the ground. The angle of elevation (this is how far up from horizontal Mark is looking) is 38°. The string is 80 feet long. How far above the ground is the kite?
