A)What is the magnitude and direction of vector a + vector b

b)What is the magnitude and direction of vector b- vector a?

I should have gotten

a)4.2m at 40 degrees east of north

b)8m at 24 degrees north of west

I am confused by this problem

Change vector b to N,E coordinates.

I get B= -2.3E + 3.3N

Now add them for part a.

A+ B= 5E -2.3E + 3.3N and that converts to the answer given.
