Part (A). You are designing the radar system to track the UFOs appearing in the city. In your setup, you have two radars R1 and R2, that are 20 miles from each other. And this happens! One day the radars detect a UFO somewhere between them. According to the data provided, the angle of elevation measured by R1 is 35 degrees. The angle of elevation measured by R2 is 15 degrees. What is the elevation of the UFO? Round your answer to the nearest thousandth mile. Part (B). Now, one of your radar stations is broken. So you have only one radar. The working radar suddenly detects another UFO. According to the data provided, the angle of elevation of the UFO from some point A on the ground is 60 degrees. After flying 15 seconds horizontally, the angle of elevation changes to 30 degrees. Also, it is detected by your working radar that the UFO is flying at a speed of 200 m/s, can you find the elevation (height) at which the UFO is flying? Round your answer to the nearest thousandth meter.
