EastWind [94]

Answer:

1229 km

Step-by-step explanation:

The missing angle is ...

180° -60° -75° = 45°

Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.

?/sin(75°) = 900 km/sin(45°)

? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km

The UFO is about 1229 km from KA-12.
