I believe there is an error in question 96 in the classwork. The x component of the vector should be positive 39.22.
Dear Peter Lepera,
Thank you for your comment. Question 96 says that the bearing of the airplane is 185 degrees, which is 185 degrees clockwise from the north direction. This would put our vector in quadrant III, making both the x- and y-components of our vector negative.
Please let us know if you have any other questions/comments.
