The resultant of A and B makes an angle of 'p' with A and 'q' with B,then:
a) p<q
b) p<q if A<B
c) p<q if A>B
d) p<q if A=B

Have a drawing. This helps a lot. I'd love to post a picture but I had some problems in uploading lately. What I suggest is that you make sketches of the pair of vectors, and find the resultants. In the first one, make the vector A longer, in the second equal to vector B and in the third, shorter than vector B. Then compare the different sizes of the angle between the resultant and your original vectors.

Hope it helped. And post your answer, so that I can check whether you understood. :)
