PLEASE HELP ME 20 POINTS In the plane shown in the figure below, lines land mare cut by the transversal line n. The eight angles at the intersections of these lines are labeled. Which of the following statements, when it is true, CANNOT always be used
to prove that lines land mare parallel?

Option (4)

Step-by-step explanation:

Since, lines l and m are the parallel lines and line 'n' is intersecting these parallel lines,

Option (1)

∠c ≅ ∠y

True.

[Corresponding interior angles]

Option (2)

∠a ≅ ∠w

True.

[Corresponding interior angles]

Option (3)

∠b ≅ ∠x

True.

[Corresponding interior angles]

Option (4)

∠b ≅ ∠z

False.

[Since, ∠b + ∠Z = 180°, consecutive exterior angles]

Option (5)

∠a ≅ ∠z

True.

[Alternate exterior angles]

Therefore, Option (4) will be the answer.

b.my answer is b.

47 - 90 = 43

43 - 180 = x

x = 137
