Question

two parallel lines are crossed by a transversal. what is the value of a? a = 43 a = 63 a = 117 a = 137

Explanation:

Step1: Identify angle - relationship

When two parallel lines are crossed by a transversal, corresponding angles are equal. Angle \(a\) and the \(63^{\circ}\) angle are corresponding angles.

Step2: Determine the value of \(a\)

Since corresponding angles are equal, \(a = 63^{\circ}\).

Answer:

\(a = 63\)
