Question

if m∠4 = 119, what is m∠10? (not drawn to scale)

Explanation:

Step1: Identify angle - pair relationship

$\angle4$ and $\angle10$ are corresponding angles. When two parallel lines are cut by a transversal, corresponding angles are congruent.

Step2: Determine the measure of $\angle10$

Since $\angle4$ and $\angle10$ are corresponding angles and $m\angle4 = 119$, then $m\angle10=119$.

Answer:

A. 119
