The value of x = 40.

Step-by-step explanation:

From the figure, it is clear that given a transversal line cuts two parallel lines m and n, thus making the corresponding congruent angles 120° and 3x°.

Here, 120° is corresponding to 3x°.

As corresponding angles are congruent.

so

3x° = 120°

Divide both sides by 3

3x/3 = 120 / 3

x = 40

Therefore, the value of x = 40.
