Answer 2

Answer:

Step-by-step explanation:

Sum of the interior angles of a hexagon is 720°

Let the sixth angle be x°

The given angles are : 100° , 110° , 120°, 130° , 140°

∴ 100 + 110 + 120 + 130 + 140 + x° = 720

∴ 600 + x = 720

∴ x = 720 - 600 = 120 °

Ans : the sixth angle of the hexagon is 120°
