Answer 1

Step-by-step explanation:

The interior angle of any regular polygon is (n-2)*180/n

so,

(7-2)*180/7

5*180/7

128.57

/ -- divided by

* -- multiplied by

Hope this helped...

Answer 2

Answer:

A heptagon has 7 sides.

A regular heptagon has all 7 sides equal.

Step-by-step explanation:

'a' is the measure of one side.

And to find the interior angles,

we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees.

$a = \frac{900}{7} = 128.57 degrees$
