Question

In Fig.,find the value of x and y and then show that AB parallel CD.
⚠️ Don't give unusual answers!!​

Answer 1

x=180-50

y=130

ab||cd

please mark as brainliest answer.....

Answer 2

$\large{\mathtt{\red{\underbrace{\overbrace{\blue{\boxed{\boxed{\pink{«ANSWER»}}}}}}}}}$

Here, ∠x+50° =180°(-- straight line)

∠x=180° −50°

∠x=130°

And ,

∠y=130°(-- vertically opposite angles)

Thus,

∠x=∠y=130°

NOW,

Using theorem:- If two lines are cut by a transversal and the alternate interior angles are congruent, the lines are parallel.

Thus,

AB//CD.
