**Just Tell Me If Its "Doable" (Vectors)**

Here's the problem:

Give magnitude and direction from the positive x axis, given A=60. Use the following picture:

*http://www.webassign.net/giancoli5/3_35alt.gif*I know how to do vectors...

Ax: 60cos(28)=52.98

Ay: 60sin(28)=28.17

Cx: 0

Cy: 46.8

B: ?

B: ?

Now correct me if I am wrong, but don't I need the angle of B in order to solve?
