5/2 = 8/x
5x = 16
x = 16/5
x = 3.2 or 3 1/5 fish
        
             
        
        
        
4g  and 6b and that's a total of 10 in all so you know it will be 1/2 if its going to be two out of two
        
             
        
        
        
The data is a little bit complex,but you can use the knowledge of vector in the subject of algebra,or you can ultimate the basic Euclidean knowledge,like cosine theorem.In detail,you can list two equation with two variable,and get the answer.but i don't finish calculating it.
        
             
        
        
        
Step-by-step explanation:
