# Angle between two vectors

The vector A has a magnitude of 6m and vector B has magnitude of 4 m. That is the angle between them if the magnitude of the resultant is (a) 3m (b) 8m?

Let vector A lie along the x-axis. Do each part graphically and by components.

#### Solution Preview

If we have two vectors A and B at an angle theta, then the resultant is given by the formula,

R^2 = A^2 + B^2 + 2 AB Cos(theta)

For the first case, R^2 = 9

9 = 36 + ...
