Best ResponseYou've already chosen the best response.1\[2x^2=12^2\]\[2x^2=144\]\[x^2=\frac{144}{2}\]\[x^2=72\]\[x= \sqrt{72}\]\[x= \sqrt{36*2}\]\[x=6 \sqrt{2}\]

Best ResponseYou've already chosen the best response.2\[x\sqrt{2} = 12\]\[x = \frac{12}{\sqrt{2}}\]\[x = \frac{12}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}}\]\[x = \frac{12\sqrt{2}}{2}\]\[x = 6\sqrt{2}\]There you go :)

Best ResponseYou've already chosen the best response.0SOH CAH TOA Sin = opposite/hypotenuse cos = adjacent/hypotenuse tan = opposite/adjacent cos(45) = x/12 cos(45)(12) = x

Best ResponseYou've already chosen the best response.1from this I noticed that you can simply get one of the sides by multiplying the hypotenuse by \[\frac{1}{\sqrt{2}}\]

Best ResponseYou've already chosen the best response.2Does it tell you if it's a right triangle?

Calcmathlete

Best ResponseYou've already chosen the best response.2It tells you that?

Calcmathlete

Best ResponseYou've already chosen the best response.2Ok. The ratio again. x, x, x√2 x = 1.2 x√2 = ?

Best ResponseYou've already chosen the best response.2By the way, if the x's get confusing because they are using x as a variable, I'll just use y.

Best ResponseYou've already chosen the best response.2Ok. Same situation. The legs are always congruent in a 454590 triangle. The hypotenuse is always in this ratio: \[Leg \times \sqrt{2}\]Can you figure it out since you have the leg?
