vector A and B lie in a plane.A has a magnitude 8.00 and angle 130° , has components Bx=-7.72 and By=-9.20.What are the angle between the negative direction of the y axis and the direction, the direction of the product of vector A* B, the direction of A*(B+3.00k)?

well, B has direction 230°
So the angle between A and B is 100°
Since Ax = -5.14 and Ay = 6.13
Not quite sure what the question is, but
you can do all the normal dot-product and projection stuff.
