Question

If the relation between vector a, vector b, vector c is a=8b and c=-7b then what is the angle between vector a and vector c

Answer 1

heya....

a = 8 b = -8/7 cHence a and c are parallel and having opposite direction.So angle between a & c is .π i.e(180°)

Answer 2

As we can clearly see here that both the vectors are in opposite direction.
When two vectors are in opposite direction, the angle between them is = 180 degrees. So, here also the angle between the two vectors will be = 180°
