Question

Fan + Medal


the measure of each interior angle and each exterior angle of a regular pentagon (a five-sided polygon).

Answer 1

interior angles of a polygon is
\[A=180(n-2)\]
for a polygon n=5
so find A, when n=5

Answer 2

so when n=5
\[A=180(n-2)=180(5-2)=540\]
so sum of interior angles=540
and each of them are=540/5=108 degree

Answer 3

how do i find the exterior

Answer 4

yes for exterior angle use
\[A=\frac{ 360 }{ n }\\n=5 ~for~polygon \]

Answer 5

ok?

Yeah! thank you very much!
