Answer:

Step-by-step explanation:

the Pythagorean theorem is

c is the hypotenuse which is the side opposite of the right angle

plug the numbers into the Pythagorean theorem

$x^2+(\sqrt{26})^2=13^2$

when squaring a square root, just take the number in the radical and get rid of the radical

$x^2+26=169$

subtract 26 from both sides

$x^2=$ $143$

find the square root of 143

143 is prime so it can just be written as

$x=\sqrt{143}$
