Hello, HonourableDragon6239!
If the major axis is ≈ 200 m, 200 ≈ 2b.
The lactus rectum is equal to 2a²/b.
It is also equal to the distance between the foci, so 2√(a²-b²).
With 2a²/b=2√(a²-b²), find a.
The long base and height of the trapezoid are equal to the distance between the foci.
The short base can be found with the Pythagorean theorem with a and the angle of 75 degrees.
