<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
