Draw a rectangle with the long sides
hor and the short sides(210ft) ver.
Draw a diagonal from the upper left hand corner to the lower rt corner.
The angle between the diagonal and the
top hor side is the angle of depression.
tan27 = Y/X,
tan27 = 210/X,
X = 210 / tan27 = 412ft = dist. from
boat to foot of lighthouse.
