Step-by-step explanation:
solution:- from LHS 1-cos²x/sinx
∵ 1-cos²x = sin²x
∴ sin²x /sinx = sinx
from RHS tanx × cosx
∵tanx = sinx×cosx
∴ sinx/ cosx × cosx = sinx
Since, LHS = RHS proved ___
you would use 1.5 packets, but that requires 2 packets.
1 packet in total would feed 8 people, and half of another would feed an extra 4. 4+8 = 12.
