Answer:
x=65
other angle= 165
Step-by-step explanation:
quadrilaterals always have a total of 360 degrees
because of this you can set up an equation and solve
360=90+40+x+(4x-95)
360=130+5x-95
360=35+5x
325=5x
65=x
plug this in to find missing angle
4(65)-95=165
 
        
             
        
        
        
Answer:
2
Step-by-step explanation:
Diagonals of a parallelogram bisects each other. 
Therefore, 
4x = 8
x = 8/4
x = 2
Or 
5x = 3x + 4
5x - 3x = 4
2x = 4
x = 4/2
x = 2
 
        
             
        
        
        
Answer:
n = 5
Step-by-step explanation:
- Move all terms not containing  n  to the right side of the equation.
7n = 31 + 4
7n = 35
- Divide each term by  7  and simplify.
n = 5
i hope this helps :)
 
        
                    
             
        
        
        
Combine your like terms: 5v + 5 = 5v +4
subtract the 5v and 4 from each side:  0 = 1
because 0
