You're in charge of the fireworks display for the neighborhood party this year. Depending on the shell size the fireworks will explode at various heights. A 10-inch shell that is fired can reach a height of 1200 feet. If it is launched at an angle of 65°, how far away (x) would someone have to be sitting to be directly under the explosion? Round your answer to the nearest foot and show all work on the whiteboard.
