Best ResponseYou've already chosen the best response.1The figure allows us to say \[\Large x\sqrt{2} = 5\]

Best ResponseYou've already chosen the best response.1You have to divide both sides by \(\Large \sqrt{2}\), then rationalize the denominator (if the book requires you to do it)

Best ResponseYou've already chosen the best response.1It's just simply \[\Large x = \frac{5}{\sqrt{2}}\] optionally you can rationalize the denominator to get \[\Large x = \frac{5\sqrt{2}}{2}\]
