Question

in fig y=108°& x=71°.are the lines m and n
parallel ? justify?
find the Answer plzzzzz​

Answer 1

Answer:

We have, x = 71°and y = 108°

Now, x + y = 71∘ + 108∘ = 179∘

So, x + y ≠ 180∘

But x and y are the interior angles formed by a transversal l of two lines m and n.

It is known that, if the sum of the interior angles formed by a transversal of two distinct lines is 180∘, then the two lines are parallel.

∴ line m is not parallel to line n.
