Explanation :
It is given that,
The radius of the earth is, r = 3959 mi
From the attached figure, we have to find the distance to the horizon from this point.
So, using Pythagoras theorem:
[tex]AP^2=OA^2-OP^2[/tex]
[tex]x^2=(R+h)^2-R^2[/tex]
[tex]x^2=(3959+4.3)^2-(3959)^2[/tex]
[tex]x^2=34065.89\ mi[/tex]
[tex]x=184.57\ mi[/tex]
The distance to the horizon from this point is 184.57 mi.
Hence, this is the required solution.
