Best ResponseYou've already chosen the best response.1This is a right triangle and Pythagorean theorem tells us dw:1436843339059:dw So you have \(5^2+8^2=x^2\). Does this make sense?

Best ResponseYou've already chosen the best response.1that should say, pythagorean theorem tells us \(a^2+b^2=c^2\)

Best ResponseYou've already chosen the best response.0after we figure out \[5^2 \] and \[8^2 \] we need x (or c or whatever side is missing) by itself so we need to square root both sides.
