Answer:

  • ∠1 = ∠4 = ∠9 = ∠12 = 95°
  • ∠2 = ∠3 = 85°

Step-by-step explanation:

Corresponding angles 1 and 9 are congruent. The angles 4 and 12 that are vertical angles to those are also congruent to those.

Linear angles 1 and 2 are supplementary. Vertical angles 2 and 3 are congruent, so both measure 180° - ∠1 = 180° -95° = 85°.
