Question

For Vectors, how do you know which axis you go off of when drawing a vector's direction. I see some going off x-axis but some going off y-axis. The picture shows the 65 degrees off the y-axis but how come it's not 65 degrees off the x-axis. Is there a reason?

Answer 1

Explanation:

Vectors in describing geographic locations are slightly different from vectors in math or science - in geography, they are always going from North-South. So it would be the y-axis going up or down where the angle is measured from.

The reason why some options have their angles marked off from the x-axis is the question is trying to confuse you: when it shows a 70-deg angle from the x-axis, the answer will be a 20-deg from North-South instead.

Answer 2

If you read the description it says you are going southeast as a pilot. The reason is because you are going Southeast, you can't go Southeast anywhere without the angle where it is for B
