WORK THIS CHALLENGE EXERCISE. A is known to be 6,500 feet above sea level; AB = 600 feet. The angle at A looking up at P is 20°. The angle at B looking up at P is 35°. How far above sea level is the peak P ? Find the height of the mountain peak to the nearest foot. Height above sea level = ft. (Hint: Draw a perpendicular from B to . Label the various angles. Compute BJ, then BP, then PQ , rounding to the nearest tenth in each step; and finally find 6,500 + PQ .)
