Question

question 2 1 pts in this figure, ab||cd and m∠1 = 110°. what is m∠5? question 3 1 pts

Explanation:

Step1: Identify angle - relationship

$\angle1$ and $\angle3$ are vertical angles. Vertical angles are equal. So $m\angle3 = m\angle1=110^{\circ}$.

Step2: Use parallel - line property

Since $AB\parallel CD$, $\angle3$ and $\angle5$ are alternate interior angles. Alternate interior angles formed by parallel lines are equal. So $m\angle5=m\angle3$.

Answer:

$110^{\circ}$
