It will take 1 minute because if the 100 cats eat 100 fish and they all get the same amount then the rate should 1 fish per cat per minute.....
        
                    
             
        
        
        
Cot x= cosx/sinx =√3
tan x= 1/ √3
cos x = √2 /2 
x= 45
tan45= 1
tan x= -4/3 
csc x= 13/5
1/sin x = 13/5
sin x= 5/13
x=22.62
tan x= 5/12
