Find the measure of the unknown interior and exterior angles in the given polygons.1. m∠a =   2. m∠b =

I'm sorry, but you didn't provide any specific polygons or values for the angles. Could you please provide more details? In general, the sum of the interior angles of a polygon is given by the formula (n-2) * 180, where n is the number of sides. The measure of each interior angle in a regular polygon (a polygon in which all sides and angles are equal) is given by the formula (n-2) * 180 / n. The exterior angle of any polygon is 360/n.
