What is the compass course of a vessel heading SSE?

A 112.5°
B 135.0°
C 157.5°
D 180.0°
AI Explanation

The correct answer is C) 157.5°. The compass course of a vessel heading SSE (South-Southeast) is 157.5°. This is because the cardinal directions on a compass rose are divided into 360 degrees, with each cardinal direction (North, South, East, West) representing 90 degrees. The intercardinal directions, such as SSE, are located halfway between the cardinal directions and represent 45-degree increments, which in this case is 157.5° (180° for South + 45°/2 for Southeast). The other options are incorrect because A) 112.5° is the course for ESE (East-Southeast), B) 135.0° is the course for SE (Southeast), and D) 180.0° is the course for due South, which is different from the given heading of SSE.
