Let:
A be the station with the 17d 15m measurement,
B be the station with the 78d 10m measurement,
C be the point on the ground directly below the balloon D.
Then:
AB = AC - BC = 10 km. ...(1)
From triangle ACD:
AC / CD = cot(17d 15m)
AC = CD cot(17d 15m) ...(2)
From triangle BCD:
BC / CD = cot(78d 10m)
BC = CD cot(78d 10m) ...(3)
