Answer:
12.2
Step-by-step explanation
The triangles are congruent, so the sides are as well. Add 6.1 and 6.1 and you will get 12.2 
 
        
             
        
        
        
If <em>n</em> = 0.151515…, then 100<em>n</em> = 15.151515…
Then
100<em>n</em> - <em>n</em> = 15.151515… - 0.151515…
99<em>n</em> = 15
<em>n</em> = 15/99 = 5/33
