Answer:
i do no sorry plz i have exam in online so sorry
 
        
                    
             
        
        
        
First, you want to identify the slopes and y-int.
Equation 1 = y = -2x + 2
Slope = -2 
y-int. = 2 or (0,2)
Equationt 2 =  y = 2x + 3
Slope = 2
Y-int.  = 3 or (0,3)
To graph, first plot the y-intercepts. Then do the slopes.
Slope = -2
Down 2 over 1 (to the right)
Slope = 2
Up 2 over 1 (to the right)
Then just connect the dots in a line! 
 
        
             
        
        
        
(29-22)*26+(26-21)*22
Cut the figure into 2 then find the unknown lengths to find each part. Add them together, and you'll get the answer.
 
        
             
        
        
        
To answer this question, you would need a protractor, which is a device that measures angle. Because this is a picture, I cannot help you. I'm sorry....
What I can tell you is that the angle is less than 90 degrees.
