Step-by-step explanation:
Given : Each of the interior angle of regular polygon is 120 degrees
To Find : find the number of sides
Solution:
Formulas of interior angle : \frac{180(n-2)}{n}
n
180(n−2)
So, 120=\frac{180(n-2)}{n}120=
n
180(n−2)
120n=180n-360120n=180n−360
360=60n360=60n
\frac{360}{60}=n
60
