Question 1449Navigation General

The correct answer is D) 270°. To determine the true bearing of the lighthouse, we need to add the course and the relative bearing. The course is 355°T, and the relative bearing of the lighthouse is 275°. Adding these two values, we get 355° + 275° = 630°. Since bearings are measured from 0° to 360°, we need to subtract 360° from 630° to get the true bearing of 270°. The other options are incorrect because they do not properly account for the relationship between the course and the relative bearing. For example, option A) 080° and option C) 085° do not correctly calculate the true bearing from the given information.
