Answer:
The battle involved the largest number of casualties of the entire war and is often described as the war's turning point due to the Union's decisive victory and concurrence with the Siege of Vicksburg.
There aren't because then gravity would be burnt up.
The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. The distance between A and B is 85.6 yds.
The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,
![c=\sqrt{a^{2}+ b^{2}-2ab.cos \theta }](https://tex.z-dn.net/?f=c%3D%5Csqrt%7Ba%5E%7B2%7D%2B%20b%5E%7B2%7D-2ab.cos%20%5Ctheta%20%7D)
where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
The three points A, B, and C will form a triangle. Therefore, using the law of cosine the measure of the third side AB can be written as,
![AB=\sqrt{(AC)^{2}+(B C)^{2} -2(AC)(BC).Cos(51.2)^{o} }](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%28AC%29%5E%7B2%7D%2B%28B%20C%29%5E%7B2%7D%20-2%28AC%29%28BC%29.Cos%2851.2%29%5E%7Bo%7D%20%20%7D)
![AB=\sqrt{(80)^{2}+(104)^{2} -2(80)(104).Cos(51.2)^{o} }](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%2880%29%5E%7B2%7D%2B%28104%29%5E%7B2%7D%20-2%2880%29%28104%29.Cos%2851.2%29%5E%7Bo%7D%20%20%7D)
![AB=\sqrt{6400+10816 -16640.Cos(51.2)^{o} }](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B6400%2B10816%20-16640.Cos%2851.2%29%5E%7Bo%7D%20%20%7D)
![AB=\sqrt{7328.4}](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B7328.4%7D)
AB = 25.6 yd
Hence, the distance between A and B is 85.6 yds.
