Missing a leg use pythagorean theorem to find the missing side

The video tutorial begins with a discussion on rectangles and their relation to triangles, focusing on how a rectangle can be divided into two right triangles. The Pythagorean Theorem is introduced, explaining that the sum of the squares of the two sides equals the square of the hypotenuse. The tutorial then demonstrates how to find an unknown side of a triangle using this theorem, emphasizing the importance of identifying the hypotenuse. The process involves applying order of operations and inverse operations to solve the equation, ultimately finding the unknown side as the square root of 55. The tutorial concludes with a simplified solution.
