I need to figure out the taper angle on a piece of wood. Can someone
help me out?? The piece is 18 7/16" long. The top is 1 11/16" wide
and
the bottom is 2 3/16" wide. What angle would I need to cut that?

Doesn't anybody know how to do simple trig anymore?

Basically you have a 1/2" taper (2 3/16 - 1 11/16") over 18 7/16" long
piece

inv cosine (.5/18.4375)
=88.44 deg.

or 1.56 deg, depending on how you want to measure it.
