Im not sure how to do this question. I included the screen shot. I have attempted and gotten incorrect answers 3 times. 

Two position vectors, A and B, are shown in the diagram below. The green arrow represents vector A while the red one represents B. The components of the vectors are as
follows:
-6 cm,
Ax
Ay
-19 cm
20 cm, B
у
В.
х
8 cm

у (ст)
40
20
x(cm
20
40
-40
-20
-20
