  1. The Horizon By: Jessica Malick, Gillian Glackin, and Josh Chaney

  2. What we’re given… x 1500 ft 20,902,231 ft (radius of Earth) 20,902,231 ft (radius of Earth)

  3. What we figured out & how… Sin90 = sinx20,903,731 20,902,231 x Sin-1(.9) = x =89◦ 20,903,731 ft(Radius of Earth + 1500 ft above Earth) 250,417.5 ft (pythagorean theorem) 20, 902, 231 ft (Radius of Earth

  4. Conclusion! • The angle you’d be looking at the horizon relative to your position directly above the ground would be about 89◦, which we found using sine inverse. • The distance to the horizon would be 250,417.5 ft, which we found using the Pythagorean Theorem.
