19. A group of college students is learning to navigate for an upcoming survival trip. On a map, they have
been given three points at which they are to check in. The map also shows the distances between the
points. However, to navigate they need to know the angle measurements.
Calculate the angle opposite the largest side, given that the distances between the three points are 34.2
km, 21.6 km, and 40.9 km.
