Slope = (0 - 6)/(4 - 0) = -6/4 = -3/2
        
                    
             
        
        
        
So you swap sides and you have 3x=93 and then you divide 3 by 93 and you get x=31
        
             
        
        
        
You can divide 87 by 3 which is 29, so each angle will be 29 degrees.
Since they are consecutive, that means they will all measure the same.
Hope this helps! :)
