10. While on a course of 138°T, a light bears 14° on the starboard bow at a distance of 8.6 miles. What course should you steer to pass 3 miles abeam of the light leaving it to starboard?

To pass 3 nautical miles abeam of a light, steer a course that creates a tangent line to a circle with a 3-mile radius centered on the light, ensuring the light remains on your starboard side. The correct course is 132T, calculated by determining the angle using trigonometry (sin θ = distance off / range) and adjusting the original course to achieve the desired tangent.
