What is the compass course of a vessel heading NNE?

Correct Answer: Option A — 022.5°

The compass rose is divided into 360 degrees. NNE is exactly halfway between North (000°) and Northeast (045°). Calculating the midpoint, 000° plus 22.5° equals 022.5°. Each cardinal point is 90°, intercardinal points are 45°, and the points between those are 22.5° increments.
