Aaron uses an angle measuring device on a 3-foot tripod to find the height, h, of a weather balloon above ground level, as shown in this diagram. The balloon is at a 42º angle of elevation. A radio signal from the balloon tells Aaron that the distance between the tripod and the balloon is 20,000 feet.   Part a: Determine k. Part b: What is height, h, of the balloon above ground level? Include units and round to the nearest integer
