Determine the direction of vector

[kgianqu2]

Find the direction of the vector . Let the direction of a vector be the angle that the vector makes with the +x-axis, measured counterclockwise from that axis. x=7.25 km, y=-3.50 km

Please help. I got -25.769, but when I entered it (to the correct sig figs) mastering physics said it was wrong.

Have you tried entering 360 - 25.769 = 334.231?

 

[kgianqu2]

That worked, thank you so much. But why did it have to be subtracted from 360?

Do they want the answer in degrees?

 

[kgianqu2]

Yes, but it I got the answer. It had to be subtracted from 360. Thank you anyway.

If the y component is negative and the x component is positive, in what quadrant will it be?
Draw a sketch if you don't see it.
