Answer:
n= 26, so the answer would be 'B'.
Step-by-step explanation:
n-8=18
n=18+8
n=26
 
        
                    
             
        
        
        
Set the equations to equal each other because the angles are equal. 
8x - 63 = 4x - 27 
+63 on both sides
8x = 4x + 36
-4x on both sides
4x = 36
/4 on both sides
x = 9
Answer:
x = 9
