Question

if the measure of angle 2 is 40 degrees what is the measure of angle 7?
140
10

Explanation:

Step1: Identify angle - pair relationship

Angle 2 and angle 7 are vertical angles.

Step2: Recall vertical - angle property

Vertical angles are congruent. That is, if $\angle2$ and $\angle7$ are vertical angles, then $m\angle2=m\angle7$.

Answer:

$40$
