If you don't remember the value of off the top of your head, it's possible to derive it with some identities and knowing that .
Consider the expression . With the angle sum identity, we have
and the double angle identities give
Write everything in terms of cosine:
Now let . Then
Let . Then
The rational root theorem suggests some possible roots are
and checking all of these, we find that is among the solution set. In fact,
We have only for odd multiples of , so it follows that
The answer would be the snake drives in for miles

Answer: they hiked 2 miles on the first day.
Step-by-step explanation:
Let x represent the distance that the group hiked on the first day.
During the second day of the hike, the group hiked twice as far as they did on the first day. This means that the distance that they hiked on the second day is 2x.
On the third day, they hiked twelve miles farther than combined distance of the first two days. This means that the distance that they hiked on the third day is x + 2x + 12
In all, they hiked 24 miles. This means that
x + 2x + x + 2x + 12 = 24
6x + 12 = 24
6x = 24 - 12 = 12
x = 12/6 = 2 miles
