Question

question given m||n, find the value of x.

Explanation:

Step1: Identify angle - relationship

When two parallel lines \(m\) and \(n\) are cut by a transversal \(t\), the 40 - degree angle and the angle with measure \(x^{\circ}\) are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. So \(x = 40\).

Answer:

40
