Answer:
≈ 1833
Step-by-step explanation:
To find ratio of proton mass to electron mass, we have to divide.
The numbers are given in <em>scientific notation</em>.
Let a number be   and another be
 and another be   , when we divide, we will follow the rule shown below:
, when we divide, we will follow the rule shown below:

Now, we use the information given to find the ratio:

This means we can find the number by taking 4 decimal places to the right, so that would becomes:

The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
 
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
1 | 4   6   - 2
         4     10
   ------------------
    4   10    8 ← remainder
  
 
        
                    
             
        
        
        
Use the sine law: sinB/b = sinA/a 
SinB = b*sinA/a 
sinB = 3*sin120° /8 
∠ B = 18.94° ≈ 19°
        
                    
             
        
        
        
Answer:
no
Step-by-step explanation:
the sides do not have the same measurments which is required of the SSS postulate
