Vector A has a magnitude of 6.0..? Please show me where I went wrong!?

Vector A has a magnitude of 6.0m and points 30 degrees north of east. Vector B has a magnitude of 4.0m and points 30 degrees west of north. The resultant vector R=A+B is given by: The answer is 7.2m at an angle of 26 degrees north of east. My work: A= 30 degrees (+) B= -30... show more Vector A has a magnitude of 6.0m and points 30 degrees north of east. Vector B has a magnitude of 4.0m and points 30 degrees west of north.

The answer is 7.2m at an angle of 26 degrees north of east.

My work: A= 30 degrees (+)
B= -30 degrees

Ax=6cos(30)=5.2
Ay=6sin(30)=3

Bx=4cos(-30)=3.5
By=4sin(-30)=-2

Rx= Ax+Bx=8.7
Ry=Ay+By=1

I'm not sure where to go next or what to do differently but I'm not getting the right answer! Thank you!!
