Best ResponseYou've already chosen the best response.1Sum of all angles of a polygon is governed by the relation S = 180*(n2) where n is the no of sides in the polygon (n greater than or equal to 3) for heptagon n = 7. therefore each angle measure = 180*(n2)/n = 180*(72)/7 = 180*5/7 = 900/7 = 128.57142857... therefore approximately 128.6. Thus option A.
