Answer:
Concept: Ordinary Mathematics 
- Just a general tip: Zoom away further from the camera to capture the question clearer.
- Calculate the Total: 31 students 
- A= 4/31= 13%
- (A+B)/31 = 14/31 = 45%
- Can't see clearly what it says 
 
        
             
        
        
        
Answer:
1800
Step-by-step explanation:
Given in the question a polygon of 12 sides
Formula to calculate sum of interior angles of 12-gon is 
<h3> (n – 2)180</h3>
where n is the number of sides 
which in this case = 12
plug values in the formula above 
(12 - 2)180
12*180 - 180(2)
2160 - 360
1800
Sum of measurements of the interior angles of a 12sided polygon is 1800
 
        
                    
             
        
        
        
-2(4g-3)= 30
 -8g+6= 30
 -8g=30-6
 -8g= 24
 G= 24/-8
 G= -3
Hope this helps!
