Question

find the sum of the angles of a polygon with 12 sides​

Answer 1

This question is about polygon in polygon some properties is there

like sum of interior angle of polygon=

$180^{\circ}(\mathrm{n}-2)$

now

as side of polygon is given as 12 sides that means (n=12)

putting the value we get

sum of interior angle of polygon

$=180^{\circ}(\mathrm{n}-2)=180^{\circ}(12-2)=1800^{\circ}$

hence final conclusion that the sum of angle of polygon having 12 side is

$1800^{\circ}$
