You are on course 180°T and take a relative bearing of a lighthouse of 225°. What is the true bearing of the lighthouse?

Correct Answer: Option A — 045°

Using the navigational formula True Bearing equals True Course plus Relative Bearing (TB = TC + RB), add 180°T and 225° to get 405°. Subtracting 360° from the sum yields the correct true bearing of 045°.
