(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
        
             
        
        
        
Answer:
Correct option: third one -> 12
Step-by-step explanation:
In a polygon with 'n' vertex, we can trace diagonals from one vertex to all vertices, except to the vertex chosen and the two adjacent vertices (because we would have sides and not diagonals), so we would have 'n - 3' diagonals.
If we have a polygon with 15 vertex, the number of diagonals from one vertex is 15 - 3 = 12.
Correct option: third one
 
        
             
        
        
        
Isolate the y to one side so we get: y = 2x - 1
The slope of the line is 2.
        
                    
             
        
        
        
The value of the tangent of an angle is the ratio (opposite side) / (adjacent side).
Here you see that the opposite side (opposite to Angle B) is of length 5 and the adj. side has length 12.
Thus, the tan of Angle B is 5/12.  (answer)
