Answer:
For the parallelogram to be a rectangle, at least one angle must be a right angle or a 90° angle, we know that:
     13x + 34° + 10x + 10° = 90°
=> 13x + 10x                   = 90° - 34° - 10°
=> 23x                            = 46°
=> x                                 = 46°/23 = 2°
 
        
             
        
        
        
Answer:
x=9/2 or 4.5
Step-by-step explanation:
 
        
             
        
        
        
Put this into slope intercept form. 
   y = 6 - x      becomes     y = -x + 6
"m" is the coefficient on x:   -1
"c" is the number without the x:   6
 
        
                    
             
        
        
        
If the value of a is positive, the line slopes upwards.
