D.EITHER STATEMENT IS SUFFICIENT. STATEMENT (1) IS SUFFICIENT BECA...

44. d.Either statement is sufficient. Statement (1) is sufficient because if the measure of each adjacentexterior angle is 72, then the measure of the interior angle is 180 – 72 = 108. Statement (2) is also suffi-cient. Regular polygons contain congruent sides and congruent angles. If the pentagon is made up of540 degrees, then 540 5 = 108 in each angle.
