sum of all interior angles of a hexagon is 720°
therefore, let the unknown angle be x
x+100+110+120+130+140= 720°
x+600= 720
x= 720 - 600
x = 120°
Therefore the unknown angle is 120°.
therefore, let the unknown angle be x
x+100+110+120+130+140= 720°
x+600= 720
x= 720 - 600
x = 120°
Therefore the unknown angle is 120°.

sum of angles of a hexagon = 720°
let the unknown angle be x
So,
100+110+120+130+140+x= 720°
x = 720° - 600
x = 120

So,
100+110+120+130+140+x= 720°
x = 720° - 600
x = 120
