In the adjoining figure, Lines $a \parallel b$, c is a transversal. Find $\angle y$."

Given :

In the given figure, $a || b$ and c is a transversal.

To do :

We have to find $\angle y$.

Solution :

We know that,

If two parallel lines are intersected by a transversal, then the alternate interior angles are equal.

Therefore,

$\angle y=55°$  (55° and $\angle y$ are alternate interior angles).

The value of $\angle y$ is 55°.
