Best ResponseYou've already chosen the best response.1(3,4) means xcoordinate = 3 y coordinate =4, so it'll be dw:1363005449516:dw can you find the hypotenuse = b= ...? using pythagoras theorem ?

Best ResponseYou've already chosen the best response.1a^2+b^2=c^2 3^2+b^2=4^2 9+b^2=16 b^2=7 \[\sqrt{7}\]

Best ResponseYou've already chosen the best response.1you've taken incorrect sides... a= 3, b=4 find c=hypotenuse =..?
