You are on course 030°T. The relative bearing of a lighthouse is 45°. What is the true bearing?

Correct Answer: Option B — 075°

True bearing equals ship's true heading plus relative bearing (TB = SH + RB). With a course of 030°T and a relative bearing of 45°, the sum is 075°T. Standard Bowditch navigational formulas govern this fundamental conversion between relative and true bearings.
