tan 22 = 168/x
x tan 22 = 168
x = 168/tan 22
x =415.81459
Rounding to the nearest tenth

Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2
Hence,
After 6 days, 3 bottles will be left.
