How do I figure the cut angle for wall trim greater than 90~

I have a wall corner that is 107 degrees rather than the normal 90 degrees. How do I figure the angle of cut for each trim pannel so the two trim pannels match up? I tried to cut the trim at 53.5 degrees but this did not work.

If two 53.5 degree angles did not match up, then the corner is not 107 degrees. If you are working with baseboard, the best thing to do would be to cope one piece so that it's profile fits right over the other one. When you cope trim this way, slight angles don;t even matter, provided the cope has been backcut so that only the face of the miter is making contact.

If you have a sliding t-bevel square, put it in the corner to find the angle, then put it on your miter saw and turn it until the blade matches the angle, and add 90. (If the miter saw says the angle is 15 degrees, it's 90 + 15, or 105 degrees, and so on.)
