You are on course 344°T and take a relative bearing of a lighthouse of 270°. What is the true bearing to the lighthouse?
Official USCG Answer & Rule Citation
Correct Answer: Option C — 254°
Using the standard vector formula TB = TC + RB, combining the true course of 344° with the 270° relative bearing gives 614°. Subtracting 360° results in the correct true bearing of 254°T.
