Second problem: If one bird flies 1.8 km West and 3.6 km North and bird two flies 3.6 km West and 1.8 km North. What is the angle between both of their resultant trajectories?

Man wish I had you as my professor. Mines got me doing it another way and its kinda confusing. I like yours because you just made it into two triangles, found both angles and subtracted, genius. Thank you.
