Question 813681
The legs of a right triangle are 4 cm and x cm. The hypotenuse is (2x-1) cm. What is x? I know the answer to this question is 3 but what I can't figure out is how that solution was achieved. I tried setting up the equation like {{{ 4x^2+x^2=(2x-1)^2}}} but got the wrong answer.
------------------
It's {{{4^2 + x^2 = (2x-1)^2}}}
