Find the value of x that makes m ∥ n, m ∥ n.

The value of x that will make m parallel to n is: 40.
According to the Converse of Corresponding Angles Theorem, the two lines cut across by a transversal line are parallel to each other if the two corresponding angles formed are congruent.
Therefore, let's find the value of x that will make m parallel to n.
[tex]3x^{\circ} = 120^{\circ}[/tex] (corresponding angles)
[tex]x = 40[/tex]
Therefore, the value of x that will make lines m and n to be parallel to each other is 40.
