Given vectors p and q are perpendicular and |p|=2|q|, determine the angle between |p-q| and |3p-6q|. (not using dot product as that was not taught yet in this unit)

If you dont know dot product just assume here that q=i and p =2j here p and q are perpendicular to each other and there mode is always satisfy the given equation here now you can find angle without using dot only by simple trignometry
