please help!! Ted is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, the angle of depression to the boat is 16°18'. When the boat stops, the angle of depression is 48°51'. The lighthouse is 200 feet tall. How far did the boat travel from when it was first noticed until it stopped? Round your answer to the hundredths place. I think I have some of it down... 200/tan(16.18) 200/tan(48.51) then subtract the solutions... is this the right path or no?
