Question 98Navigation General

The correct answer is C) 157.5°. A vessel heading SSE (South-Southeast) is on a course of 157.5°. This is because the 360-degree compass is divided into 16 equal points, each covering 22.5 degrees. South is 180°, and Southeast is 135°, so South-Southeast (SSE) is the midpoint between these two, which is 157.5°. The other options are incorrect because A) 112.5° is too far to the east (East-Southeast), B) 135.0° is Southeast, and D) 180.0° is directly South, which is not the same as SSE.
