We have a right triangle....
The Earth's radius (3959 miles) forms one leg and the Earth's radius plus the 15.6 miles forms the hypotenuse
And "x" is the other leg
So.... using the Pythagorean Theorem
x^2 + 3959^2 = (3959 + 15. 6)^2
x^2 = (3959 + 15.6)^2 - 3959^2 take the square root of both sides
x = √[ (3959 + 15.6)^2 - 3959^2 ] ≈ 351. 8 miles
See if you can do numbers 2 and 3.....they are similar to this one
