Find the angle between two vectors ` vec a\ a n d\ vec b ,\ if:| vec a|=3,\ | vec b|=3\ a n d\ vec adot vec b=1`

Explanation

To find the angle between two vectors \(\vec{a}\) and \(\vec{b}\), we can use the formula for the dot product:

\[ \vec{a} \cdot \vec{b} = |\vec{a}| |\vec{b}| \cos \theta \]

Where:
- \(\vec{a} \cdot \vec{b}\) is the dot product of the vectors,
