Using the Pythagorean Theorem, determine the length of the missing side of the right triangle.

10 in.

Step-by-step explanation: We can use the PT to find the length of the missing side. The PT is + = , where "a" and "b" are side lengths and "c" is the hypotenuse. Given that, we can see that they have given just one side length (24 in) and the length of the hypotenuse (26 in). Plugging these values into the formula, we get 24^2 + b^2 = 26^2. This equals 576 + b^{2}  = 676. Solving for b^{2}, we move the 576 and do 676-576, which equals 100, giving us b^{2} = 100. If we take the square root of both sides, we get b = . The square root of 100 equals 10, giving us our final answer. The length of the missing side is 10 in.
