Assume Mount Everest goes up and down at a constant rate. Both sides of the mountain start at 14,000 feet above sea level and the peak is at 29,000 feet above sea level. If the slope goes up by 30 degrees, what is the length of the mountain?
90,000 ft.
Work: 29,000 - 14,000 = 15,000
30 degrees = 30/90x or 1/3x.
15,000 * 3 * 2 (as it goes both ways) = 90,000
