Two hikers come to a fork in the road, where the paths diverge at an angle of 39 degrees
Hiker A heads down one path at 6.2 km/h, while hiker B moves down the second path at 5.4 km/h.
After travelling for an hour and a half, hiker A shoots up a flare that rises 0.8 km into the air.
With what angle of elevation (to the nearest degree) does the hiker B see the flare when it is
at its highest point?
