Answer:
Step-by-step explanation:
hello : 
 sin x + 2 sin x cosx = 0   equivalent to : sinx(1+2cosx) =0
sinx=0 means :  general solution is  : x= kπ....k in Z
1+2cosx=0  means : cosx= -1/2 general solution is : x= ±π/6+kπ...k in Z
 
        
             
        
        
        
Step-by-step explanation:
a.120÷100×20
profit=24
=24+120
=144
b.289÷100×15
=43.35
289-43.35
=245.65
