Answer:
- explained and given below.
explanation:
(a)
∠1 and ∠8 = 130°, corresponding angles are equal
(b)
∠4 = 130°, vertically opposite angle to ∠1
∠6 = interior angles add to 180°, ∠6 = 180° - 130° = 50°
(c)
∠3 = adjacent angles add to 180°, ∠3 = 180° - 130° = 50°
∠5 = interior angles add to 180°, ∠5 = 180° - 50° = 130°
(d)
∠3 and ∠6 = 50°, alternate angles are equal
