A glider lands 18 miles west and 5 miles south from where it took off the result of the trip can be described by the vector (-18,-5) use distancs for magnitude and direction to describe this vector a second way.

I believe its south of west but not sure if 19,16 0r 16,19

19 is the miles and 16 is the angle going south of west

Steve · Answer

well, of course it's south and west; they told you that. Where did the 19,16 come from?

distance: √(18^2+5^2) = √349 = 18.68
angle: tanθ = -5/-18, so θ=195.5° = W15.5°S, or a bearing of 254.5°
