You effectively can’t just talk to women on dating sites. Thanks to how matching works, you have to successfully sell yourself with pictures to get your profile read, and successfully sell yourself with words in the profile before you can actually talk with anyone.
Back before matching was a thing, it wasn’t much better. You could talk but you’d usually be ignored because the woman’s inbox would be filled with too much crap for her to go through it all.
Right, but why bring theta into it at all? TV screens are as a hypotenuse (a²+b²) with a fixed ratio (a/b=16/9), so you just need to solve for a and b.
