Thank you for using Pythagoras for me. My lazy ass got to thinking what is the short side going to be and said fuck it. Not thinking I could probably get it by using the 16:9 ratio

Yeah, I used 16:9 to get the short side, then pythag for the diag.

You're welcome, every math teacher who has had to hear "But when will I ever *use* this in real life?!" lol
