Step-by-step explanation:
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 i 180°, then the two lines are parallel
:: line m is not parallel to line n.
