Using the interior angle sum theorem for finding x of a pentagon

The video tutorial explains how to calculate the sum of interior angles of a pentagon and solve for an unknown variable X. It begins with an introduction to the properties of a pentagon, followed by a step-by-step calculation of the sum of its interior angles. The tutorial then demonstrates how to set up and solve an equation to find the value of X, using angle measurements and combining like terms. The process is broken down into clear sections, making it easy to follow and understand.
