206. You are steaming on a course of 071° T at 19 knots. At 1907 you observe a lighthouse bearing 122° T. At 1915 the lighthouse bears 154° T. What is your distance off at the second bearing

The distance off at the second bearing is determined by calculating the distance run between bearings, identifying the triangle's angles using the course and bearings, and applying the law of sines to solve for the unknown side representing the distance off, resulting in approximately 3.7 miles.
