not sure what Upper B means
Answered by Anonymous
It should be Vector B instead of Upper B
Answered by Steve
when you say A times B, is that the dot product, or the cross product?

The dot product
Answered by Damon
|A| |B| cos theta = A dot B

2.2 * 10 * cos theta = 14

theta = cos^-1 (14/22)

theta = 50.5 degrees
