Now all these lines are *curved* because they're on the surface of a

If you know where the satellite is, the simplest way would be
to measure the distance on an atlas, and work out the angle subtended
at the earth's centre from that.
This would not require any _spherical_ trigonometry.

Ah! A Flat-Earther!
