Alright, lets get started.
As the diagram shows, the line from point P is tangent to earth's curvature.
It means it is making right angle.
So the triangle formed will be right triangle.
Hence we can use Pythagorean theorem in it.
So from point P to center of earth, it will be hypotenuse of triangle.
taking square root, the x will be :
hence the value of x is 216.2 miles. : Answer
