Homework Statement
Vectors A & B lie in an xy plane. A has a magnitude 7.4 and an angle 142(deg) with respect to the +x direction. B has components (-6.84i, -7.37j)
B) What is the angle between the -y axis and the direction of the Cross product between A and B?

The Attempt at a Solution
So I layed out my grid.
i----------j-------k
(-5.83)----(4.55)----(0) (A->)
(-6.84)---(-7.37)----(0) (B->)
I got the -5.83 & 4.55 from the formula (7.4cos142, 7.4sin142)
Welp, I added everything up and got 74.1
Wiley plus isn't accepting it. I have everything else right on this problem save for this part. The answer is expressed in degrees. I very much gave this question an honest amount of attempts. Running out./:
