Question

find the sum of interior angle of a polygon with: 80 sides . And answer is 14040 degree ( wrong will be strictly reported).​

Answer 1

$\underline{\textsf{Given:}}$

$\textsf{Number of sides of the polygon is 80}$

$\underline{\textsf{To find:}}$

$\textsf{Sum of the interior angle of the polygon}$

$\underline{\textsf{Solution:}}$

$\textsf{we know that,}$

$\textsf{Sum of interior angles of an n-sided polygon is}$

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

$\mathsf{=(80-2){\times}180^{\circ}}$

$\mathsf{=78{\times}180^{\circ}}$

$\mathsf{=14040^{\circ}}$

$\underline{\textsf{Answer:}}$

$\textsf{Sum of the interior angles of the polygon is}$

$\mathsf{14040^{\circ}}$
