It's basically the theory that the earth is at the center of our cosmos rather than the sun.
Explanation:
cos 62=base/hypotenuse=8/AC
AC=8/(cos62)=11.87cm
sin62=perpendicular /hypotenuse
sin62=AC/BA
BA=11.87/sin62=16.05cm
Any options? A reason US joined the war was because German subs destroyed lusitania which had Americans on it. That's one of the main reasons we joined the war, if that's a option for your question then that's it.
If that is not a option let me know and i can further assist
