Answer:Step-by-step explanation:Answer:See belowStep-by-step explanation:OneThe measure of all the exterior angles of a convex n-gon always add up to 360 degrees.So the exterior angles of a triangle = 360 degreesThe exterior angles of a 4 sided figure = 360 degreesThe exterior angles of a 12 sided figure = 360 degrees.===== TwoSame answer as One. All polygons have this property as long as they are convex.======ThreeThe relationship between the number of sides and the actual size of the exterior angle isSides = 360/angle sizeangle size = 24Sides = 360 / 24Sides = 15 sidesFourBe careful. This is an interior angle questionGiven: sum of interior angles = 7380Formula: Total of interior angles = (n - 2)*180Solution(n - 2) * 180 = 7380 Divide both sides by 180(n - 2) * 180/180 = 7380/180 Do the divisionn - 2 = 41 Add 2 to both sidesn - 2 + 2 = 41 + 2 Collect like termsn= 43
