Answer 1

Answer:

Given:

A regular heptagon (a figure with 7 sides)

Formula used:-

Sum of interior angle of a polygon=(2n-4)×90°

$Each \: \: interior \: \: angle= \frac{Sum \: \: of \: \: interior \: \: angle \: \: of \: \: a \: \: polygon</p><p>}{number \: \: of \: \: sides}$

Solution:-

n=7 sides

Sun of interior angle of a heptagon=(2n-4)×90°

={2(7)-4}×90

=(14-4)×90

=10×90°

=900°

Each interior angle=

$= \frac{900}{7}$

=128.571°

=128.57

a=128.57°
