okay, let altitude of rocket be h. a is distance from station a to right below the rocket. Same for b. Apparently the ground is 1 dimensional if I follow the diagram there.

h/a = tan 41
h/b = tan 75
a + b = 20

Solve for h.

The height of the rocket = (20/cos(26º))sin(41º)sin(75º) ≈ 14.101214005174410452295201629320274304784929791725907218028808999657728184124
