Precise text rotation angle (turn-off rotation alignment)

Hi there! I am using Miro for drawing some complex geometrical-based schemes to describe ITIL-concepts.

When I try to align text according triangle side I stuck with sticky alignment which forces text to freeze rotation arounbd 45 degrees. And if I got triangle side angle 48-50 degrees I have no chance for perfect alignment.

Please add any method I could use to do that.
