Answer:
720 degrees.
Step-by-step explanation:
The sum of the interior angles of a convex polygon with  n  sides is
180(n - 2)  degrees.
In this case,  n = 6 sides, so the angle sum is
180(6 - 2) = 180(4) = 720 degrees.
The reason this works is that if you draw a diagonal from one vertex to the others (see attached image), you get 2 fewer triangles than the number of sides.  Each triangle contains a total of 180 degrees, so the total of all the interior angles is 180(n - 2).

Answer:
The value of n = -10  
Step-by-step explanation:
Given the points
Finding the slope between (3, n) and (4,0) 

As slope = 10
using the formula
Slope  =  [y₂ - y₁] /  [x₂ - x₁]
so substituting the values
       10   =  [0 - n] / [4 - 3]
       10   = -n / 1
      10 = -n
      n = -10    
Therefore, the value of n = -10  
 
        
             
        
        
        
Answer:
19,27 cm^2
Step-by-step explanation:
area of triangle = (6 x 3)/ 2 = 9 cm^2 
circle area : 3^2 x 3,14 = 28,27 cm^2 
area of shaped region = 28,27 - 9 = 19,27 cm^2
