A)find the x component of their vector sum r

B)find the y component of their vector sum r

C)The magnitude of r

D) the angle r makes with the positive diretion of the x axis.

the book said that the answers should be:

A)-1.59m

B)12.1m

C)12.2m

D)82.5 degrees

Can you help me? I don;t get how you get these answers

Your description of directions begs for amplification. I recommend you change both vectors to x,y coordinates.
