Best ResponseYou've already chosen the best response.1neither can i because what you need to know is ratio of a 306090 right triangle are \[1:\sqrt3:2\] for short leg : long leg : hypotenuse

Best ResponseYou've already chosen the best response.0well i already know the answer because i am using a ACT prep book i just need to know how to figure it out for future

Best ResponseYou've already chosen the best response.1there is no other way to say it than just to say it that actually happens to be one of your answer, but so would \[2,2\sqrt3,4\]

Best ResponseYou've already chosen the best response.1it is always true that the ration of a 306090 right triangle are \[\huge 1:\sqrt3:2\] what is what you need to know it is a fact

Best ResponseYou've already chosen the best response.0so its just basically a rule i need to know? no real figuring here?

Best ResponseYou've already chosen the best response.1so for example if the short leg hat measure \(10\) then the long leg would have measure \(10\sqrt3\) and the hypotenuse would measure \(20\)

Best ResponseYou've already chosen the best response.1you can derive it, but you don't want to have to do that on the fly remembering is best
