Understanding Laptop Screen Dimensions and the Pythagorean Theorem

The video tutorial explains how to determine the width of a 15-inch laptop screen using the Pythagorean theorem. It begins by describing the problem and the properties of a right triangle. The tutorial then demonstrates how to apply the Pythagorean theorem to find the unknown side of the triangle, which represents the screen's width. Finally, it shows how to simplify the square root to obtain the exact value of the width.
