From the top of a lighthouse 210 feet high, the angle of depression to a boat is 27. Find the distance from the boat to the food of the lighthouse. The lighthouse was built at sea level.
Help me!

height/distance=tan27
distance= height/tan27
Who would ever build a lighthouse at sea level? You build bouys at sea level.
