An aircraft (at Z) is spotted by two observers (at X and Y ) who are L=1050 feet apart. As the airplane passes over the line joining them, each observer takes a sighting of the angle of elevation to the plane, as indicated in the figure. If A=35∘, and B=30∘, how high is the airplane? The elevation of the plane is approximately feet. (Do not round until the final answer. Then round to two decimal places as needed.)
