Question

what is the measure of n?

Explanation:

Step1: Identify angle - pair relationship

The angles of measure $27^{\circ}$ and $n$ are alternate - interior angles.

Step2: Apply the property of alternate - interior angles

When two parallel lines are cut by a transversal, alternate - interior angles are congruent. So $n = 27^{\circ}$.

Answer:

$27^{\circ}$
