Question

lines m and n are parallel. what is the value of x?

Explanation:

Step1: Identify angle - relationship

When two parallel lines are cut by a transversal, corresponding angles are equal. The angle of $38^{\circ}$ and the angle of $x^{\circ}$ are corresponding angles.

Step2: Set up the equation

Since corresponding angles are equal, we have $x = 38$.

Answer:

38
