Steps to solving any vector addition problem:

1.  Break each vector (A, B, C, etc) in to its horizontal, , and vertical, , components.

 

2.   Add all horizontal components (Ax, Bx, Cx, etc.) together to get the horizontal component of the resultant (Rx)

 

3.   Add all vertical components (Ay, By, Cy, etc.) together to get the vertical component of the resultant (Ry)

4.   Determine the magnitude of the resultant:

 

5.   Determine the direction of the resultant:

 

 

6.   Does it make sense? In particular, make sure to add 180 degrees if Rx is negative!
