Answer:
1) ∠3 and ∠6
2) ∠8 = 75°
Explanation:
1) Angles 3, 4, 5, 6 are "interior" angles, as they are between the parallel lines. Angles 4 and 5 are on alternate sides of the transversal, so are "alternate interior angles," as are angles 3 and 6.
___
2) Angles 4 and 8 are corresponding, hence congruent.
m∠8 = m∠4 = 75°
