Solve for the missing side length using the Pythagorean theorem ex 2

The video tutorial explains how to use the Pythagorean theorem to find a missing side length in a right triangle. It begins with an introduction to the theorem, followed by identifying the hypotenuse. The tutorial then demonstrates solving for the missing length using the equation a^2 + b^2 = c^2. Finally, it covers simplifying the square root to find the exact value of the missing side.
