Arnie is sitting at the edge of a lake, flying a kite. The lenght of the kite is 85m. He estimates the angle of elevation to the kite to be 30°. What is the length of the kite above the water?
We can see that the kite should be perpendicular to the water. And so the other angle will be 60 degrees. It's a special triangle. So if the length of the kite is 85m then the length of the kite above water is 85/2 [tex] \sqrt{x} [/tex]
