A right triangle and two of its side lengths are shown in the diagram. Which measurement is closest to the value of x in feet?

To find the missing side length \( x \) in a right triangle, we can use the Pythagorean theorem, which states:

\[
a^2 + b^2 = c^2
\]

Here, \( a \) and \( b \) are the lengths of the two legs of the triangle, and \( c \) is the length of the hypotenuse.

If you provide the lengths of the two sides of the right triangle, I can help you solve for \( x \).
