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.
I hope this helped :)

Step-by-step explanation:
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>
