Question

the interior angle of regular polygon is 156 degree find the number of sides of the polygon​

Answer 1

Answer:

$\frac{180(x - 2)}{x} = 156$

$180x - 360 = 156x$

$- 360 = - 24x$

$15= x$

Answer 2

Answer:

Sum of interior angle= (n-2) 180=156

(N-2) 180=156

180n-360=156

180n=156+360

180n-156=360

24n=360

N=360/24

N=15sides
