What is the size of each interior angle of a 12-sided regular polygon?

What is the size of each interior angle of a 12-sided regular polygon?

Answer Details

Interior angle = (n - 2)180
but, n = 12
= (12 -2)180
= 10 x 180
= 1800
let each interior angle = x
x = $\frac{(n-2)180}{n}$
x = $\frac{1800}{12}$
= 150o
