Applying the pythagorean theorem to find the missing length of a triangle

The video tutorial explains how to find the missing side of a right triangle using the Pythagorean theorem. It begins by identifying right triangles through the 90-degree symbol and explains the roles of the hypotenuse and other sides. The tutorial then demonstrates how to apply the Pythagorean theorem to solve for the missing side, using algebraic manipulation to find the value of x. The solution is left in its square root form without decimal approximation.
