Satellites ka-12 and sal-1 have spotted a ufo. scientists want to determine its distance from ka-12 so they can later determine its size. the distance between these satellites is 900 \text{ km}900 km900, space, k, m. from ka-121212's perspective, the angle between the ufo and sal-111 is 60^\circ60 ∘ 60, degree. from sal-111's perspective, the angle between the ufo and ka-121212 is 75^\circ75 ∘ 75, degree. how far is the ufo from ka-121212? do not round during your calculations. round your final answer to the nearest kilometer.
