Question 181993: Ok so i have this problem which using methods my dad suggested can not be solved, there is a test this Tuesday and i need a method that makes sense, please help me. Using Pythagerus's Theorum (if that's how you spell it) A squared + B squared = C squared, if A = 12, B = x and C = 2x, what is the value of x?

A%5E2%2BB%5E2=C%5E2
%2812%29%5E2%2B%28x%29%5E2=%282x%29%5E2
144%2Bx%5E2=4x%5E2
3x%5E2=144
x%5E2=48
x=sqrt%2848%29=4sqrt%283%29

It's "o" after "g" in his name, Pythagoras.
