To prove a similarity of a triangle, we use angles or sides.
In this case we use angles to prove
∠ACB = ∠AED (Corresponding ∠s) 
∠AED = ∠FDE (Alternate ∠s) 
∠ABC = ∠ADE (Corresponding ∠s) 
∠ADE = ∠FED (Alternate ∠s) 
∠BAC = ∠EFD (sum of ∠s in a triangle) 
Now we know the similarity in the triangles. 
But it is necessary to write the similar triangle according to how the question ask. 
The question asks " ∆ABC is similar to ∆____. " So we find ∠ABC in the prove. 
∠ABC corressponds to ∠FED as stated above. 
∴ ∆ABC is similar to ∆FED
Similarly, if the question asks " ∆ACB is similar to ∆____. " 
We answer as ∆ACB is similar to ∆FDE. 
Answer is ∆ABC is similar to ∆FED.
        
             
        
        
        
First, get the difference between the price level changes.

Then, divide it by the initial price level, which is 109.

Multiply by 100 to get its percent.

Thefore, the inflation rate during the year is 3.67 percent.
 
        
             
        
        
        
1345/99 = 13.585858
