Any polygon has sum of exterior sides as 360°

No of sides

  • 360/60=6

#25

Let the angles be 2x and 7x

  • 2x+7x=189
  • 9x=180
  • x=180/9
  • x=20°

Smallest angle=2(20)=40°

Answer:

40° and 6

Explanation:

25. Let's suppose the angles as 2x and 7x

Then,

2x + 7x = 180°

or, 9x = 180°

or, x = 180°/9

or, x= 20°

Now, 2x is smaller

So, 2x = 2× 20° = 40°

26. Solution,

Each exterior angle = 360°\n

or, 60° = 360°/n

or, 60°n = 360 °

or, n = 360°/60°

or, n=6

As, Hexagon has 6 sides.
