What is the compass course of a vessel heading NNE?

A 022.5°
B 045.0°
C 067.5°
D 090.0°
AI Explanation

The correct answer is A) 022.5°. On a compass rose, the cardinal direction of North-Northeast (NNE) corresponds to 22.5° on the compass. This is because the 32 points of the compass are evenly spaced at 11.25° intervals, with each cardinal direction (N, E, S, W) falling on the 0°, 90°, 180°, and 270° marks respectively. The direction midway between North and Northeast is therefore 22.5°. The other options are incorrect because 045.0° represents Northeast (NE), 067.5° represents East-Northeast (ENE), and 090.0° represents East (E), which do not match the given direction of North-Northeast (NNE).
