Adding Vectors Graphically:

2m/s @65 degrees and 6m/s @ 320 degrees
20 m @ 90 degrees and 5 m @200 degrees

break each vector into components, then add.

2@65
i component 2cos65
j component 2ain65
6@320
i component 6coa320
j component 6ain320

Add the i component, then the j components. Then add those as vectors
