The answer would be 30 degrees because points F, G, H, and J are collinear, all you would have to do is figure out /_GHK by subtracting 180 degrees from it.
Like this  :
JHK = 180 degrees - 120 degrees = 60 degrees
 
        
             
        
        
        
Answer:
The correct answer for this equational ratio is x = 5
Step-by-step explanation:
In order to calculate for x, we must create the necessary ratios

Cross multiply to get
900 - 100x = 80x
900 = 180x
x = 5
 
        
             
        
        
        
(3 yard/sec) x (3,600 sec/hr) x (1 mile / 1,760 yard) = 
   (3 x 3,600 / 1,760)  (mile/hour)  =  6.136... mph (rounded)
        
             
        
        
        
The matchup are:
- (1st picture): y=2x+3 and y=x+5
- (2nd picture): y=4x+2 and y =3x+2
- (3rd picture): y=2x+1 and y =x+2
- (4th picture): 3x and x+3
<h3>What does the graph of an equation shows?</h3>
The graph of the linear equation is known to be one that often brings or  set the  points that can be found on the coordinate plane and it is one that shows all the solutions to the equation. 
Note that when  all variables stands for real numbers, a person can be able to use graph to show the equation and this is often done through plotting the points to show a pattern and then link up the points to have all the points.
From the above, the pictures that have all the points as shown on the graph are:
- (1st picture): y=2x+3 and y=x+5
- (2nd picture): y=4x+2 and y =3x+2
- (3rd picture): y=2x+1 and y =x+2
- (4th picture): 3x and x+3
