Question

Each interior angel of a polygon is 140.find the number of side

Answer 1

Answer:

9

Step-by-step explanation:

We know that :-

Each interior angle of a polygon = 180 - each exterior angle

Then, 140° = 180° - each exterior angle

each exterior angle = 40°

Now ,

each exterior angle = 360/ n

where n is the number of side

=> 40 = 360/n

=> n = 360/40

=> n = 9

The number of sides is 9

Answer 2

Answer:

Step-by-step explanation:

Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides. n = 9 sides. Hence the number of sides is 9 sides.
