7) The angle of depression from the top of the lighthouse to a boat is
6º. If the lighthouse is 130 feet
above sea-level, what is the
horizontal distance from the
lighthouse to the buoy? Round your
answer to the nearest whole
number.
1130 ft

Explanation:

An observer in the top of a lighthouse determines that the angles of depression to two sailboats directly in line with the lighthouse are 3.5 º and 5.75º. If the observer is 125 feet above sea level, find the distance between the boats.
