The International Space Station orbits Earth at an altitude of about 240 miles. In the diagram, the Space Station is at point E. The radius of Earth is approximately 3,960 miles. To the nearest ten miles, what is EH, the distance from the space station to the horizon?

are there options ?

Step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
