By the Pythagorean theorem (for right triangles):
${c}^{2}={a}^{2}+{b}^{2}$
where a and b represent the lenght of the legs and c represents
the lenght of hypotenuse.
$a=7,b=24,c=x$
${x}^{2}={7}^{2}+{24}^{2}=49+576=625$
Next, we obtain the value of x by taking the square root:
$x={\sqrt{x}}^{2}=\sqrt{6}25=25$

$x=25$
