How do I calculate an angle of a surface?

Question

I want to angle this cylinder to have the same angle as the top surface of this wedge.

How do I match the exact angle of the surface to the cylinder?

Besides calculating the angle manually via trigonometry - you can actually snap and align objects to faces.

Turn on snaps, select face. Turn on Align rotation with the snapping target.

After you snap it, the angle should be displayed in the cylinder's transform.
