Answer:
20.1246118 or 20.12
Step-by-step explanation:
First draw the box with the diagonal, as you can see it is split into 2 equal right triangles. Now use the pythagorean theorem (a^2+b^2=c^2) to find the length of the diagonal
 
        
             
        
        
        
X is Kevin; Y is Dan
X = 3Y
X - 4 = 5(Y - 4)
3Y - 4 = 5(Y - 4)   
3Y - 4 = 5Y - 20 
     + 4         +4
4 cancels each other out.
     3Y = 5Y - 16 
     - 5   -5
5 cancels each other out.
    -2Y = -16  
    /2       /2     
       Y = 8 
X = 3Y;    
X = 3 x 8; 
Thus,
X = 24;
Kevin(x) is 24
