Question

find the measure of angle x,
given a || b.

x =

Explanation:

Step1: Use the property of parallel lines

When two parallel lines \(a\parallel b\) are cut by a transversal, corresponding angles are equal.

Step2: Identify the corresponding angle

Here, angle \(x\) and the \(42^{\circ}\) angle are corresponding angles.

Answer:

\(42\)
