C-16-Q093mediumsingle_mcq

Each interior angle of a regular polygon with $n$ sides is —

a $\dfrac{180°(n-2)}{n}$
b $\dfrac{360°}{n}$
c $\dfrac{180°}{n}$
d $90° - \dfrac{180°}{n}$

ব্যাখ্যা

The sum of all interior angles of an $n$ -sided polygon is $180°(n-2)$ , and in a regular polygon these angles are equal. Dividing by $n$ gives each interior angle as $\dfrac{180°(n-2)}{n}$ .
