Answer:
i will just give you the answer <u><em>1e+45</em></u>
Step-by-step explanation:
 
        
                    
             
        
        
        
the picture in the attached figure
we know that
area of the triangle is equal to

in this problem
A=47 in²
b=x
h=x
so

therefore
the answer is
x=9.7 in
 
        
                    
             
        
        
        
A line parallel to the y-axis that passes through (77,88) is x = 77.  There is no slope-intercept form of this equation if our coordinate system is based upon a horizontal x-axis and a vertical y-axis.
 
        
             
        
        
        
No.Because 14/2=7 and 7*3=21 so $21 is the answer.
