Kind of also depends of which angle of view you devote yourself to.

The ones they usually give you are the diagonal ones like with TV's.

I find those next to meaningless and deceptive. Divisive. And derivative.

It's the horizontal angle of view you need as if yore shooting a row of
buildings or a row of people sitting on a couch in a small room or whatever
you need to know how may buildings or people you can squeeze in.

Few are going to get it by turning there camera on an 45 or 33.3 degree
angle.
Although I just did last week to get a standing guy with his dog at his
feet. And try to as often as I can.

There are PORTRAIT format shots.
And there are LANDSCAPE format shots.
And then there are *%&^#%^ format shots
    as in the above.
You can hang those any way you want. You don't even have to hang it
straight.
Perfect for the igloo in your backyard. In the winter.

I've got this formula put in my Filemaker database calculation field
Degrees(2*Atan((FILM Format Dimension/2)/FOCALLENGTH))
FOCALLENGTH is a field which is in each record which I enter manually.
And FILM FORMAT DIMENSION is another field in each record I enter myself.
Then the ANGLEOFVIEW calculation field gives me the calculation based on
those two fields I had entered myself.

This WHOLE POST I entered myself!
