I really need help. Someone please help me with this.
9966 [12]

Answer:

  angles 1, 3, 6, 8 = 142°

  angles 2, 4, 5, 7 = 38°

Step-by-step explanation:

Vertical angles and corresponding angles are congruent, as are alternate interior angles. Hence the angles 1, 3, 6, 8 are all congruent:

  ∠1 = ∠3 = ∠6 = ∠8 = 142°

Each of the remaining angles forms a linear pair with one or another of those, so is its supplement:

  ∠2 = ∠4 = ∠5 = ∠7 = 180° -142° = 38°
