Answer 1

Answer:

$x\sqrt{2} = c$

Step-by-step explanation:

The Pythagorean theorem tells us that $a^2+b^2=c^2$, where a and b are the legs of a right triangle. If the length of each leg is x, we know by applying the theorem that $x^2+x^2=c^2$, so $2x^2=c^2$. Applying the square root on both sides we get $x\sqrt{2} = c$
