An aircraft (at Z) is spotted by two observers (at X and Y) who are L= 2000 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= 50°, and B= 45°, how high is the airplane? Y. The elevation of the plane is approximately (Do not round until the final answer. Then round to two decimal places as needed.) feet,
