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

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

substitute in the formula and solve for n





so
The regular polygon has 9 sides
therefore
The regular polygon is a nonagon
-3b+ac=4
Move c to the left and - 3b to the right
ac-c=-4+3b
Now factor by c at the left
c(a-1)=-4+3b
Divide the right by a-1
C=(-4+3b)/(a-1)
