Answer:

  • Hexagon = 720°
  • Dodecagon = 1800°
  • 14-gon = 2160°
  • Nonagon = 1260°
  • Decagon = 1440°

Step-by-step explanation:

Sum of interior angles = (n-2)180°

Hexagon = 6 sides

  • (6-2)180°
  • (4)180°
  • 720°

Dodecagon = 12 sides

  • (12-2)180°
  • (10)180°
  • 1800°

14-gon = 14 sides

  • (14-2)180°
  • (12)180°
  • 2160°

Nonagon = 9 sides

  • (9-2)180°
  • (7)180°
  • 1260°

Decagon = 10 sides

  • (10-2)180°
  • (8)180°
  • 1440°
