How to calculate angle from 2D projection
$begingroup$
I have picture of interior wall. I know that angles A and B are 90deg in reality and I need to calculate angle C.
A in picture is 95 deg
B 123 deg
C 142 deg

You cannot find the real angle C from just the projection angles. The only thing you can know from the picture is that the angle C isn't larger than 142°.
