Answer:
580
Step-by-step explanation:
because you square the area and identify 
 
        
             
        
        
        
D. You times 5y by 8y then 3
        
                    
             
        
        
        
To set this up you will set the two angles equal to 180° since it is a straight line
This will make the equation x+6x+19=180
Combine like terms. 7x+19=180. 
Subtract 19 from both sides. This will make it 7x=161
Divide both sides by 7. That will make it x=23
Next plug in the x to solve for abc. 7(23)+19. This equals 157
X= 23
Hope this helped :)
        
             
        
        
        
Since they are complementary angles, then the sum of the measure of both angles is 90
So, M/_5 + m/_6 = 90
13+ X = 90
x=77 
measure of angle 6 is 77
