circle tangent to 3 lines

How to draw a circle of unknown rad. tangent to 3 lines that are not parallel or square to each other?
I see there is a circle tangent to 3 circles but not 3 lines.

anyone help here?

Look at Circle Inscribed.

Welcome @klunker!

Just try Circle tangent to 3 circles, it will work with lines too.

I can't seem to find circle inscribed.

As far as trying the tangent to 3 circles I swear I tried it a couple of days ago.
I couldn't select lines, just circles.

Tried it again today and it works.

Silly me.

Not new to CAD, been working on them since the late '70's or early '80's.
Can't say exactly when.
Back when they had to run on main frames.

Computervision Cadds 3 I think was the first one I used.
Was my full time job designing Large Automotive Progressive dies.

Thanks to both of you for your help.

Probably you are using an older version not having circle inscribed yet.
