Question

find x , y if ab || cd​

Answer 1

Answer:

x = 130°

y = 130°

Step-by-step explanation:

We see that 50° and x are in a line, forming a linear pair.

So,  x + 50° = 180°

∴ x = 180° - 50° => 130°

Now, we also see that x and y are a pair of alternate angles.

As we know alternate angles are equal, x = y = 130°.

∴ y = 130°

Answer 2

Answer:

x = 130,y = 130

Step-by-step explanation:

ab || cd

then angle x = angle y (alternate interior angles)

angle y = 130 (vertical opposite angles)
