Let $\theta$ be the angle between $\mathbf{a}$ and $\mathbf{b}.$  Then
\[\|\mathbf{a} \times \mathbf{b}\| = \|\mathbf{a}\| \|\mathbf{b}\| \sin \theta.\]From the given information, $7 = 14 \sin \theta,$ so $\sin \theta = \frac{1}{2}.$  Thus, the smallest possible value of $\theta$ is $\boxed{30^\circ}.$
Question:
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.
Answer:
Let's think step by step.
