Answer:
IJ = 34
Step-by-step explanation:
Since HK = JK, then IK is a perpendicular bisector and Δ is isosceles, then
IJ = HI , that is
2s = s + 17 ( subtract s from both sides )
s = 17
Then
IJ = 2s = 2 × 17 = 34

5(j+11)
Step-by-step explanation:
 
        
                    
             
        
        
        
116 1/4 = 465/4 and 2 2/9 = 20/9
(465/4)÷(20/9) will be the answer and it is equal to 52 flags
