A tunnel for hydroelectric power is to be constructed through a mountain from one reservoir to another at a lower level. The distance from the top of the mountain to the lower end of the tunnel is 5.32 miles, and from the top of the mountain to the upper end of the tunnel is 2.63 miles. The angles of depression of the two slopes of the mountain are 42.7° and 48.8°, respectively. 42.7° 48.8° 2.63 mi 5.32 mi Tunnel
