What does it mean by "between diagonals of the parallelogram"? I did scalar product of AB and AC though I got the wrong answer. I tried other vectors though I kept getting an error whenever I subbed the values in my calculator.
You just need to find the angle between AB and AC, I think. It's the dot product divided by the product of the magnitudes of the vectors, if that makes sense
If you draw a line from one corner to the opposite corner of the parallelogram,that's a diagonal. Repeat for the other 2 corners and that's he othe diagonal. They meet at a point and you're finding the acute angle between them, not the obtuse angle.

Done that but not got the same answer as one in mark scheme
