In the figure, lines , m, and n are parallel. A classmate says you can use the corollary to the side- splitter theorem to find x. Explain your classmate's error. 12 m 20 15

The corollary to the side-splitter theorem states that if a line is parallel to one side of a triangle and intersects the other two sides, then it divides those two sides proportionally. However, in this scenario, the line m is not intersecting two sides of a triangle, but rather two lines. Therefore, the corollary to the side-splitter theorem cannot be applied in this case to find the value of x. Your classmate's error is in misapplying the theorem in the given context.
