How can I cut a piece of wood to make a 30 degree slope with the ground?

I’m sorry, I don’t really understand this question. I think you might want to try again, and rephrase.

I need to mark a piece of wood for a 30 degree cut.
user
Alright, in that case, it seems like you’re using the word “slope” to refer to an angle.  Can you tell me what you’re doing, and why?  And are you using a “wood” you mean

I just need to mark the wood with a pencil for a 30 degree cut.
user
Oh, you need to make a mark for a cut, a mark that indicates where the cut will be, to make a cut.  Can I know more about what you’re trying to do?

Oh, I understand!  To mark something with a pencil, you could just use a “pencil”, but if you already have a “pencil”, then I suggest you use the other part of the word.  Let’s try again with what you wrote.  I think you’re trying to say that you need to mark a wooden piece with a pencil so that it’s 30 degrees.  Is that right?
