    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.
