How to set chamfer angle in Blender?

Question

Blender

I have a question about blender. I need to make a chamfer, but not at the angle that the blender offers me... How can I organize this? Can I choose my corner somewhere and chamfer? Tell me more please, otherwise I'm in a blender quite recently.) Thank you in advance.
Ps Sorry if this question has already been asked, maybe I didn't search well :)

Answer 1

Ctrl + B and at the same time enter the value of the angle on the keyboard with numbers.
You can also play around with Ctrl + R
