Best ResponseYou've already chosen the best response.0so just plug a and b in and then you take the square root of c

Best ResponseYou've already chosen the best response.1This is called the Pythagorean theorem \[\huge~\rm~a^2+b^2=c^2\] dw:1439387408714:dw \[\huge~\rm~8^2+4^2=c^2\] \[\huge~\rm~64+16=c\]

Best ResponseYou've already chosen the best response.1right you might need to use a calc for that when you do you get a decimal \[\huge~\rm~8.944272 \]

Best ResponseYou've already chosen the best response.1Here you use the Pythagorean theorem which is a^2 + b^2 = c^2 a and b are the legs of the triangle while c is the hypotenuse. All you have to do is fill in the variables and solve for c. Therefore, (8)^2 + (4)^2 = c^2 64 + 16 = 80 But because 80 is c^2, you have to square root it. \[\sqrt{80}\] = \[4\sqrt{5}\] and that's your final answer.
