A Global Positioning System satellite orbits d = 15,500 miles above Earth's surface (see figure). Find the angle of depression from the satellite to the horizon. Assume the radius of Earth is 4000 miles. (Round your answer to two decimal places.)
Consider the given figure.
Suppose that the satellite is situated at the point S.
By the above figure,
Clearly, the distance from the center of the earth O to the satellite is 40...
