To use the Pythagorean theorem, we need to identify the lengths of the two known sides of the right triangle. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be expressed mathematically as:
\[ a^2 + b^2 = c^2 \]
where \(c\) is the length of the hypotenuse, and \(a\) and \(b\) are the lengths of the two other sides.
Unfortunately, the information provided does not specify which side lengths are given or which side we are trying to find. Please provide the lengths of the sides or indicate which one is the hypotenuse, and I can help you calculate the unknown side length!
