If the quadrantal bearing of a line is N 30° W, then the whole circle bearing of the line is

1. 120°
2. 210°
3. 300°
4. 330°

Correct answer: 330°

Solution

Quadrantal bearing N 30 W is measured 30 degrees toward west from north, so the whole circle bearing = 360 - 30 = 330 degrees. The stored 300 deg is incorrect.
