You are on course 357°T and take a relative bearing of a lighthouse of 180°. What is the true bearing to the lighthouse?

Official USCG Answer & Rule Citation

Correct Answer: Option D — 177°

Applying the formula True Bearing equals True Course plus Relative Bearing (357° + 180° = 537°), and subtracting 360° because the sum exceeds a full circle yields 177°T as the exact true bearing of the lighthouse.
