Question

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

x =

Explanation:

Step1: Use the property of parallel lines

When two parallel lines are cut by a transversal, alternate - interior angles are equal.

Step2: Calculate the value of \(x\)

Since \(a\parallel b\), and \(x\) and \(31^{\circ}\) are alternate - interior angles. So \(x = 31^{\circ}\)

Answer:

\(31\)
