Physics:

For the vectors A and B in the figure use the method of components to find the magnitude and direction of a.) THe vector sum A + B, b.) the vector difference A - B, c.) The vector difference B - A.

in the figure

A is 12 m West

B is 18 m 37 N of E

im not sure how to do vector sum but i think it will be from the head to tail...

but i dunno how to form it... same as vector difference... can u help me with this?

thank you! in advance
