Answer:
x = 14
Step-by-step explanation:
110 + 5x = 180
-110 -110
5x = 70
divide by 5 on both sides
x = 14
to find y add 70 + 40 + missing angle = 2y
missing angle is 70 because 70+40+70 = 180
so 2y = 110 
y = 55
 
        
                    
             
        
        
        
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
