Oou I know this!!!! It 0.5 because the point F is at -1 and point G is at 2.
Soooo,
-1, 0, 1, 2
-1, -0.5, 0, 0.5, 1, 1.5, 2
Sooo the answer is 0.5 !!!
We know that the law of sines states that:

For simplicity, let:

In triangle A1BC this leads to:

Therefore:

Now, triangle A2BC is isosceles which means that both the base angles are equal, since angle CA1B and A2A1B are supplementary we have:
6.00037 x 10^6 is the answer in scientific notation
The volume equals length x width x height so multiply all of those with a calculator and you’ll get your answer hope I helped :)
