Chapter 2 - Acute Angles and Right Triangles - Section 2.5 Further Applications of Right Triangles - 2.5 Exercises - Page 81: 2

When a bearing is given as N, then an acute angle measure $\theta$ and then E (or W), we would draw an angle of $\theta$ to the east (or west) measured from the positive y-axis. When a bearing is given as S, then an acute angle measure $\theta$ and then E (or W), we would draw an angle of $\theta$ to the east (or west) measured from the negative y-axis.

This is how we can draw angles with the information given in the question: When a bearing is given as N, then an acute angle measure $\theta$ and then E (or W), we would draw an angle of $\theta$ to the east (or west) measured from the positive y-axis. When a bearing is given as S, then an acute angle measure $\theta$ and then E (or W), we would draw an angle of $\theta$ to the east (or west) measured from the negative y-axis.
