Question

|A + B | = |A |+ |B| what is the angle between A and B

Answer 1

Answer:

f a is the angle between (A+B) and A, then the angle between (A-B) and A will be 90 -a. Therefore, the angle between (A+B) and(A- B) is a+ 90 -a = 90 degree. It depends on the values of A and B vectors and angle between them. then angle between vectors A+B and A -B is 90°
