Question

A global angle is an angle with the positive x-axis (considered to be an angle of 0°), and the terminal angle as the angle formed after a counterclockwise rotation. What is the global angle of 20° south of west?

a) 110°

b) 70°

c) 200°

d) 340°

Answer 1

The global angle of 20° south of west is 200°.

Step-by-step explanation:

The global angle of 20° south of west can be calculated by adding 180° to the angle. This is because the positive x-axis is considered to be 0°, and angles measured counterclockwise from the positive x-axis are positive. Since south of west is in the third quadrant, it is 180° away from the positive x-axis. Adding 180° to 20° gives us a global angle of 200°.
