Given the properties of a rectangle determine the value of x

The video tutorial explains how to determine the length of a line segment in a rectangle using the properties of diagonals. It starts by identifying the given lengths and the problem statement, then discusses the properties of rectangle diagonals, which bisect each other. The tutorial proceeds to solve for the variable X using these properties and calculates the length of the line segment US. The process is summarized by emphasizing the use of geometric properties to solve the problem.

What is the length of side US based on the calculations provided?

How do you determine the total length of the two sides discussed?
