Answer:
117, 55, 54, 77, 130, 7h + 5x, 14
Step-by-step explanation:
 
        
                    
             
        
        
        
A) 3, 5, 6 
 c squared = a squared + b squared 
 6 squared = 5 squared + 3 squared
 36 = 25 + 9
 36 ≠ 34 (not a right triangle)
b) 13, 12, 5
 c squared = a squared + b squared 
 13 squared = 12 squared + 5 squared 
 169 = 144 + 25
 169 = 169 (is a right triangle) 
c) 17, 15, 9
 c squared = a squared + b squared 
 17 squared = 15 squared + 9 squared 
 289 = 225 + 81
 289 ≠ 306 (not a right triangle) 
d) 12, 8, 6
 c squared = a squared + b squared 
 12 squared = 8 squared + 6 squared 
 144 = 64 + 36
 144 ≠ 100 (not a right triangle) 
hope this helps!!
