Question

Each interior angle of a regular polygon contains 120·. Then the number of sides in the polygon are​

Answer 1

Answer:

(180 - n)2 = 120n

360 - 2n = 120 n

360 = 120n + 2n

360 = 122n

n = 360/122

THIS IS NOT A REGULAR POLYGON

Answer 2

Answer:

6

Step-by-step explanation:

Using interior angle formula- 180(n-2)/n

• 120 = 180(n-2)/n
• 120n = 180n = 360
• 360 = 60n
• 360/60
• 6 = n

Hence,the number of sides are 6..
