Five of the interior angle of a hexagon are equal if the size of the sisth angle is 155,what is the size of each of the five equal angle
2 answers
sum of interior angles of a hexagon
= 180(6-2) = 720 , from 180(n-2)
5x + 155 = 720
5x = 564
x = 113°
= 180(6-2) = 720 , from 180(n-2)
5x + 155 = 720
5x = 564
x = 113°
