Vectors Angle Determination 1
If $ \mathbf{a} $ and $ \mathbf{b} $ are vectors such that $ \|\mathbf{a}\| = 2, $ $ \|\mathbf{b}\| = 7, $ and \[\mathbf{a} \times \mathbf{b} = \begin{pmatrix} 3 \\ 2 \\ 6 \end{pmatrix},\]then find the smallest possible angle between $ \mathbf{a} $ and $ \mathbf{b}, $ in degrees.
