First, we know this diagram consists of two horizontal lines cut by a transversal line. Therefore, we know that the given angle that measures 113° and the angle we want to find are alternate interior angles. Since all alternate interior angles are equal, we know the unknown angle must also be 113°.

I hope this helps.
Since it's an alternate interior angle it would be the same as the other angle which happens to be 113 degrees.
