Question

A satellite is 13,200 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the Earth’s surface. The diagram is not to scale.
13,793 miles
17,200 miles
9,793 miles
16,552 miles

Answer 1

first fill in the drawing with the appropriate numbers

Answer 2

so we can see that

leg 1: 13200
leg 2: 4000
leg 3: x+4000

which allows us to say


13200^2 + 4000^2 = (x+4000)^2

solve for x to get your answer

Answer 3

no

Answer 4

17,200?

Answer 5

sounds like you're guessing at this point

Answer 6

all you need to do is solve 13200^2 + 4000^2 = (x+4000)^2 for x

Answer 7

have a look at this page

Answer 8

or you can do

x = sqrt(13200^2 + 4000^2) - 4000

to get x

Answer 9

ohhh so its 9,793?

Answer 10

yep

Answer 11

thank you!

Answer 12
