Answer:
I am not so clear about this question
 
        
             
        
        
        
Cos(68)=z/24
Z=24cos(68)
Find the answer by the calculator 
Second question,
Cos(x)=16/34
X=cos^-1(16/34)
Use calculator
        
             
        
        
        
To figure this out, always divide y by x in each table. All of the values have to be equal or the table isn’t proportional. 
In this case, the last choice is proportional.
