Step-by-step explanation:
By taking ( x = 18°)
<u>L.H.S</u>
cos(3x)=sin(2x)
cos(3x) = cos( 3X18°)= cos (54°)
             = cos[ 90° - (2x18°)]           ∵[  90°- (2x18°) = 54°]
             = ∴ sin ( 2x18°)
       As (x = 18°)
             = sin (2x) = R.H.S
 
        
             
        
        
        
To find out how many brothers they have, they need to multiply 4×1= 4 
So there are 4 brothers.

Area of Circle= 


                      = 

 x 

                      = 490.87

Area of Oven tray= 60cm x 50cm
                            = 3000

: . # tin that can hold on bake tray= 3000

 / <span>490.87

                                 = 6.11
Thus making it logically 6..... </span>
