Sheet Metal Bending

Good evening everyone.

Here's my problem, I'd like to bend (deform?) a sheet metal with a central V-cut, so that my two vertices meet at a certain height represented by my construction line, except and this is the reason for my presence here, I can't do it.

I am attaching screenshots of the piece in question, if I have ever expressed myself badly or if there is a lack of information, do not hesitate to let me know.

Good evening
Regards
