Both equations are equivalent, so there are infinitely many solutions.
 
        
             
        
        
        
Answer:
64
Step-by-step explanation:
 
        
             
        
        
        
7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
        
                    
             
        
        
        
By using pythagoras theorem where
 (Base)^2 +(perpedicular)^2 = (hypotenuse)^2
So,
(5)^2 +(12)^2 = (hypotenuse)^2
25 + 144 = (hypotenuse)^2
169 = (hypotenuse)^2
 13 = hypotenuse
 So, hypotenuse = 13
