Answer:
109, Corresponding angles postulate
Step-by-step explanation:
Angle 2 and the angle that’s 71 degrees are supplementary.
Just subtract 180 - 71 = angle 2
For the second box…
Alternate exterior angles is wrong (means congruent)
Vertical angles is wrong (means congruent)
Same-side interior angles is wrong (angle that’s 71 degrees is clearly outside)
Corresponding angles is RIGHT (Supplementary and the angle that’s 71 degrees is outside, and angle 2 is inside, so it’s corresponding.)
Alternate interior angles is wrong (means congruent)
