Hey there! :D
We will use the properties of similar triangles to figure this out. 
We will use two triangles inside the kite, with sides with the value of "x". 
Smaller triangle:
Smaller side= 11
Bottom side= x
Bigger triangle:
Smaller side= x
Bottom side= 25

Cross multiply. 
25*11= 275
x*x= 

Find the square root. 
√275= 16.583.... 
Or 5√11. 
I hope this helps!

Solving The Problem From Eaxh Side Is Easier
        
             
        
        
        
75x+2=
75x-2=-2. move the 2 to the other side
75x=-2 now divide 75 both sides 
75/75x=-2/75 
x=-2/75
        
             
        
        
        
X = y + 12. You then substitute or plug in that from the first equation into the second equation. You get (y+12)+y=18, then you simplify to get your y value. In this case y = 3. The you can plug your y value into either equation. (x+3=18) or (x-3=12) or (x=3+12) either way you get x=15 and y=3.
