Vector A has a magnitude of 3.0 m and direction 1o3 degrees relative to the positive x-axis. Vector B has magnitude 5.0m and direction 215 relative to the positive x-axis.
For the resultant
I did Rx= 3 cos 103 + 5 cos 215
Ry=3 sin 103 + 5 sin 215
Then sqrt Rx^2 + Ry^2 and got 4.77
1) The resultant R has direction?
less than 90 degrees
between 90 and 180
between 180 and 270
between 280 and 360
I do not know how to figure this out. Thank you.
