    9) A)sum of exterior angle always 360degrees. B)sum of interior angle of a pentagon is: (5-2)*180= 540degrees. therefore statement (b) is true. 10) A)sum of exterior angle always 360degrees. therefore, number of sides= 360/20=18 B)let k be the number of sides. given sum of interior angles is 3240 degrees. so, (k-2)*180=3240. so, k= 20. therefore statement (b) is true
