# A right triangle measures 6 feet on one side and 3 feet at the base. The Pythagorean Theorem can be used for solving for the length of the third and unknown side. Explain the Pythagorean Theorem.

The sum of the squared length of the two known sides gives you the length squared of the third and unknown side opposite the right angle.

Explanation

The best way to solve this problem is to use the Pythagorean Theorem. The formula states that you can add the squared length of the two known sides adjacent to the right angle and that will give you length squared of the third side opposite the right angle, also called the hypotenuse. Option "B" is correct. The formula for the Pythagorean Theorem is expressed as $$A^{2}+B^{2}=C^{2}$$
