Question

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

Explanation:

Step1: Use property of parallel lines

When two parallel lines are cut by a transversal, corresponding - angles are equal. Here, since \(l\parallel m\parallel n\), the angle \(x^{\circ}\) and the \(45^{\circ}\) angle are corresponding - angles.
So \(x = 45\)

Answer:

\(x = 45\)
