Answer 1

Answer:

x+50

∘

=180

∘

(Linear pair)

⇒x=130

∘

Also, y=130

∘

(Vertically opposite)

Now, x=y=130

∘

(Alternate interior angles)

Alternate interior angles are equal.

∴AB∥CD.

Answer 2

Answer:

x = 50 degree

Step-by-step explanation:

all angles of a triangle add up to 180 degree

therefore - angle x = 180-(60+70)

= 180 - 130 = 50 degree
