Answer:
50 degrees
Explanation:
When two parallel lines are cut by a transversal, same side interior angles are supplementary.
In the figure, parallel lines AB and CD are cut by the tranversal shown forming 8 angles. Angles 3 and 6 are same side interior angles, so they are supplementary. That means that their measures have a sum of 180 degrees.
m<3 + m<6 = 180
130 + m<6 = 180
m<6 = 180 - 130
m<6 = 50
