I have a Geometry Question

Question

The International Space Station orbits Earth at an altitude of 240 mi. What is the distance from the space station to Earth’s horizon to the nearest mile?

Answer 1

Draw and label a diagram.

The radius of the earth is 3963 mi.

The station is 4203 mi above the center of the earth

The distance to the horizon is the long leg of right triangle.

4203² = 3965² + d²
