Question

how many sides does a regular polygon have if each of its interior angle is 150 degree

Answer 1

Let $n$  be the number of sides of a regular polygon then each of its interior angles is given as

$\frac{(n-2)180^\circ}{n}=150^\circ$

$6(n-2)=5n$

$n=12$

Thus regular polygon has 12 sides

$<b>$

Let,
N, be the number of sides of a regular polygon then each of its interior angles is given as

(n-2)180°/n=150°

6(n-2)=5n
6n-12=5n
n=12

Hence ⤵
regular polygon has 12 sides↩
