Corner angle calc?

[Kari]

Anyone have a suggestion on how to calc an interior angle given 3 points without inversing 2 azimuths/bearings? Seems to be a bit of a long method inversing and using the calculator to solve an angle.

Inverse point to point to point then hit the "info" button located toward the southeast corner of the screen. Scoll to the bottom to find the "angle right".

Thank you Sir. I'll have to look there again with my eyes open this time.
