Answer:
<h2>The distance to the Eath's Horizon from point P is 352.8 mi, approximately.</h2>Step-by-step explanation:
You observe the problem from a graphical perspective with the image attached.
Notice that side is tangent to the circle, which means is perpendicular to the radius which is equal to 3,959 mi.
We have a right triangle, that means we need to use the Pythagorean's Theorem, to find the distance to the Earth's Horizon from point P.
The hypothenuse is 3959 + 15.6 = 3974.6 mi.
Therefore, the distance to the Eath's Horizon from point P is 352.8 mi, approximately.
