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

A 135°
B 270°
C 045°
D 180°
AI Explanation

The correct answer is C) 045°. To determine the true bearing of the lighthouse, we need to add the relative bearing (225°) to the course (180°T). The true bearing is calculated by adding these two values, which results in 045°. The other options are incorrect because: A) 135° is the opposite of the relative bearing. B) 270° is 90° to the right of the course. D) 180° is the opposite of the course direction.
