Q: ABCD is base of a square pyramid of side 2 units and V is the vertex. The pyramid is symmetrical and of height 4 units. Calculate acute angle between AV and BC, giving your answer to 1 d.p. Here's my w/o: AV = sqrt(17) Answer is 76.4. Not sure how to get it, this question is in the vectors sectors btw.
