Below is the solution:
Use Pythagorean Theorem:
<span>radius of Earth squared + distance to horizon squared = distance from center of earth to Space Station squared. </span>
<span>4000^2 + x^2 = 4240^2 </span>
<span>x^2 = 1977600 </span>
<span>x = 1406.27</span>
Drawing a diagonal means to connect a vertex with another non-adjacent vertex.
So, for each vertex, we have 8-3=5 possible diagonals. This leads to a total of 8*5=40 diagonals.
We have to divide this number by 2 though, because in this way we're counting each diagonal twice (connecting points AB or BA gives the same diagonal).
So, an 8 sided shape has 20 diagonals.
Change 3/4 to decimal. It becomes 5.75%. To cange to a decimal move the decimal point left 2 places and
drop the percent sign. Answer: .575
