Question

1. In Fig. 3.28, find the values of x and y and then show that AB || CD. Fig. 3.28​

Answer 1

Answer:

x=130=y

Step-by-step explanation:

x+50=180 [Straight Line]

x=180-50=130

y=130[vertically oppposite angles]

<x=130 [Corresponding angles], Hence AB||CD

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

x = 130 Degree

y = 130 Degree

By the property of alternate interior angle we can conclude that this axiom supports that ab and cd are parallel

So, ab||cd
