9514 1404 393

Answer:

  ∠7 = 51°

  ∠8 = 129°

Step-by-step explanation:

All of the obtuse angles are congruent, as are all of the acute angles. The acute and obtuse angles are supplementary.

  ∠8 = ∠1 = 129°

  ∠7 = 180° -129° = 51°

Additional comment

Technically, angles 1 and 8 are called "alternate exterior angles." As such, they are congruent. Angles 7 and 8 form a "linear pair." As such, they are supplementary.
