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?
