OpenStudy (misty1212):

hi i bet you know one theorem, and probably not two

OpenStudy (sagewilson):

I'm guessing the 30-60-90 triangle one and pythagorean theorem?

OpenStudy (sagewilson):

and hello

OpenStudy (misty1212):

forget the 30 - 60 - 90 one , whatever that is use pythagoras, you can do it in your head

OpenStudy (misty1212):

\(5^2+8^2=25+64=?\) is all you need

OpenStudy (sagewilson):

All I need is the sum which would be 89

OpenStudy (sagewilson):

so it would be the square root of 89?

OpenStudy (misty1212):

yes

OpenStudy (sagewilson):

oh, that was a lot easier then I expected. Thanks Misty

OpenStudy (misty1212):

you are welcome now put that knife down...

OpenStudy (sagewilson):
