#### Answer:

Recall that the sum of the squares of the legs is equal to the square of the hypotenuse in a right triangle

#### Explanation:

Thus, the square of 13 is equal to the square of 12 plus the square of the missing leg.

We can set up an equation with x as the unknown length.

Thus, the missing side is 5 inches.
