Answer: 14.967
Step-by-step explanation:
Use Pythagorean Theorem to find the missing length.  
a² + b² = c²        
x² + 10² = 18²      
x² + 100 = 324         [Subtract 100 from both side]  
           x²= 224        
       √x² = √224     [solve the square root from both sides]
         x   ≈  14.967
