Answer 1

$\huge\mathfrak\red{☟ \: \: answer \: \: \: ✎}$

Find: sum of all interior angle of pentagon Solution: we know that, sum of all interior

$angle = (n-2)x180°$

$Now \: for \: Pentagon n = 5$

$= (5 - 2) \: x \: 180°$

$= 3x180°$

$=540°$

Answer: sum of all interior angle of pentagon

Answer 2

Answer:

1. angle=(n−2)x180°

Now \: for \: Pentagon n = 5NowforPentagonn=5

= (5 - 2) \: x \: 180°=(5−2)x180°

= 3x180°=3x180°

=540°=540°
