This is what it says:
From the top of a light house 210 feet high, the angle of depression of a boat is 27 degrees.Find the distance from the boat to the foot of the lighthouse.The lighthouse was built at sea level.
we're supposed to round the measure of the segments to the nearest hundredth.The answer I got was 66.4.Is this correct?

Draw it out as a triangle, then use tangent to solve. The height of the lighthouse is the opposite angle from the angle of depression, and the distance to the boat is the adjacent angle.
tan x = opp / adj
tan 27 = 210 / distance
0.5095 = 210 / distance
distance = 210 / 0.5095 = 412.15 ft
