Answer:
Explanation:
Formula
a^2 + b^2 = c^2
Remark
The horizon point is where x and 3959 meet.
Givens
a = 3959
b = x
c =3959 + 5.9 = 3964.9
Solution
3959^2 + x^2 = 3964.9 ^2
15673681 + x^2 = 15720432.01 Subtract 15673681 from both sides
x^2 = 15720432.01 - 15673681 Combine
x^2 =46751.01 Take the square root of both sides
sqrt(x^2) = sqrt(46751.01)
x = 216.2
If you round anywhere but at the end, an error will creep in that will make your answer incorrect.
