One of the sides of a triangle is actually a line that extends outwards on both sides. Two exterior angles are formed, namely, the two angles formed on the line that are supplementary to the triangle's original interior angles.

If one of the exterior angles is $80$ degrees and the other exterior angle is $130$ degrees,

What is the measure of the interior angle that does not touch the line?


$30$ degrees


$50$ degrees


$100$ degrees


$60$ degrees
