Question

answer them please please​

Answer 1

Answer:

Look at attached image.

1. No, x and y should be alternate but this is not the case

2. No, answer is contradiction when looking at angles a and c individually

Step-by-step explanation:

1. x = y ≠ 180

 50 + 50 ≠ 180

 x and y should be alternate but this is not the case.

2. a = 50 ⇒ b = 130º (alternate)

   c = 130 ⇒ b = 50º (supplementary)

when looked at a, and you find out it's angle it contradicts to the answer when you look at c
