I was given the following information: There is a frame $B$ which is rotated relative to frame $A$ and they share the same origin. The following vectors are in frame $A$: $(2, 1, 2)$ and $(-1, -2, 2)$. These two vectors also happen to lay on the $x$ axis and $z$ axis of Frame $B$ respectively.
I am tasked with finding the axis of rotation, and I also need to find the angle at which the frame $B$ was rotated in relation to frame $A$.
Through my knowledge I was able to find that the angle at which the frame was rotated was approximately 48.2 degrees, but I am unsure if this is correct and am unable to find the axis of rotation. I feel like I am missing something critical yet simple here.
