Answer:
The triangles are similar
Step-by-step explanation:
We are given and two angles  so by default we know the third angle.  We know the three angles are the same, so the triangles are similar by AAA.  We do not about conqruency without a side length.
 
        
                    
             
        
        
        

This then means,

which is the pythagorean trig identity. This concludes the proof.
Therefore, if  , then
, then 
 
        
             
        
        
        
N + d = 30
0.05n + 0.10d = 2.20

0.235 = 235/1000= 47/200
Answer: 47/200
