Question

Find sum of angles of a regular pentagon(internal angles).

(Hint: Use formula to find the interior angle of 5 sided polygon
​

Answer 1

/* We know that,

Sum of the interior angles of a polygon of "n"

sides is (n-2) × 180°. */

$Here , Number \: of \:sides \: in \: a \: regular$

$pentagon (n) = 5$

$\red{ Sum\: of\: the\: interior \:angles \:of\: the}$

$\red{ pentagon }$

$= ( 5 - 2 ) \times 180\degree$

$= 3 \times 180\degree$

$= 540\degree$

Therefore.,

$\red{ Sum\: of\: the\: interior \:angles \:of\: the}$

$\red{ pentagon } \green {=540\degree }$ •••♪
