Trouble with mitering this corner

[ourkid2000]

Howdy folks,

Having a little trouble trying to miter some quarter round to fit this corner. It's screwing with my brain.

I measured the angle of that wall (from short wall to long wall) to be 139 degrees. Anyone have a tip?

Thanks!

Seems to me that would only work at a roughly 90 degree corner.

Wait, now I'm confused............you can't miter greater than 45 degrees.

yeah, cut the right piece on the right of the blade at 49 degrees "left". it will sit flush against both walls.

cut the left piece on the left side of the blade at 49 degrees left also.

"Back cut" or cope the left piece at a 45 degree angle.
