@MegaBEANER1000 You can only use the pythagorean theorem when you have a Right Triangle

way too complex when u could just use the cosine rule...

Thanks a lot Khan trigonometry used to be a weak point for me since I met you

@WishFredWasDead it means A squared + B squared = the square root of c.so on a question if you figure out A measures 5 and B measures 6,to get C you square 5(so you do 5x5 = 25)and B squared (6x6 = 36)add them together to get 61,then you find the square root of 61 to give you what the C angle is.Khan talks about this on a video.(I think it`s called introduction to algibra)I think I give it to you right but it`s worth checking out just to be sure :)
