Answer:

The regular polygon is a nonagon

Step-by-step explanation:

<u><em>The correct question is</em></u>

What is the name of the regular polygon that each interior angle measures 140ﾟ?

we know that

The formula to find the sum of the interior angles in a regular polygon is equal to

$n(a)=(n-2)180\°$

where

n is the number of sides of the regular polygon

a is the measure of each interior angle of the regular polygon

we have

$a=140\°$

substitute in the formula and solve for n

$n(140\°)=(n-2)180\°$

$140n=180n-360$

$180n-140n=360$

$40n=360$

$n=9\ sides$

The regular polygon has 9 sides

therefore

The regular polygon is a nonagon
