A mountain climber stands at the top of Mount Everest at an altitude of 8848 meters above sea level and looks to the horizon. For this problem, assume that the Earth is a sphere of radius 3957 miles. a) How far away (in miles) is the horizon that the climber sees? We are looking for the straight -|ine distance from the climber's eyeball to the point on the horizon, not the distance along the surface of the Earth. b) Find the distance (in miles) along the surface of the Earth from the point on the horizon to a point at sea level that is directly beneath the climber. 4. Choose one ofthe above problems. Describe the process (in words) that you used to arrive at your answer to that problem, describe why you chose this process, and describe why this process works. Try to be as descriptive and specific as possible. Try to use as few mathematical symbols as possible
