A vector A makes on angle 30° with the y-axis in anticlockwise direction. Another vector B makes on angle 30° with the x-axis in clockwise direction. Find angle between yectors A and B.

A vector A makes on angle 30° with the y-axis in anticlockwise direct

1.	A vector A makes on angle 30° with the y-axis in anticlockwise direction. Another vector B makes on angle 30° with the x-axis in clockwise direction. Find angle between yectors A and B.
Answer» SOLUTION : From the diagram the angle between `vec(A)` and `vec(B)` is `30^(@) + 90^(@) + 30^(@) = 150^(@)`
