Question

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

Explanation:

Step1: Identify angle - relationship

When two parallel lines are cut by a transversal, corresponding angles are equal. Here, the angle of $56^{\circ}$ and the angle with measure $x^{\circ}$ are corresponding angles.

Step2: Set up the equation

Since corresponding angles are equal for parallel lines $l\parallel m\parallel n$, we have $x = 56$.

Answer:

$56$
