@ninjazeus99 If you have all three angles on a triangle and you know a side, you can use any one of them you feel like. There's more than one way to skin a cat.

@MrFK2 Theta is the Greek term/word used to describe an angle, there's more meanings, but that the only one I know.

@ninjazeus99 i think you just use sin first... cos second, tan last, but id google it :D

the sqrt of 65 is 8,06 - and the hypotenuse can be a decimal number, therefore you can just write h as 8,06

Does trig work for non right-angle triangles? Or do you have to first chop up such triangles into a bunch of right-angled ones, and go from there?

@MrFK2 A delicious kind of greek cheese that goes great on salad.
I think you mean theta however. It's just the variable that is traditionally used when talking about an angle.

I'm so happy you are "re-doing" your older videos with your nice new writing skills! Would you consider teaching us about General Relativity?

@spinynorman1982 OMG. I asked khan the same thing a few days ago. This is scary lol. I asked if he could do videos on general relativity and tensor calculus.
