Question
Four of the interior angles of a hexagon measure 92°92°, 100°100°, 94°94°, and 140°140°. The remaining two angles each measure (x−32)°. What is the value of xx? Justify your response.(1 point)
 
 
  • The sum of all interior angle measure is 540°540°, so each angle measuring (x−32)° has a measure of 246°246°. Thus, (x−32)°=246°, and so x=275.
  • The sum of all interior angle measure is 720°720°, so each angle measuring (x−32)° has a measure of 294°. Thus, (x−32)°=294°, and so x=326.
  • The sum of all interior angle measure is 720°720°, so each angle measuring (x−32)° has a measure of 147°147°. Thus, (x−32)°=147°, and so x=179.
  • The sum of all interior angle measure is 540°540°, so each angle measuring (x−32)° has a measure of 123°123°. Thus, (x−32)°=123°, and so x=155
