A satellite, B, is 17,000 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the Earth’s surface.
{The picture is a circle with point O in the center, point C is on the top center edge of the circle, point a is on the upper left side of the circle and point B is outside of the circle above the circle and point C.}
13,464 miles
17,464 miles
20,957 miles
21,000 miles
Thank You so much! I'm sorry I couldn't get the picture to post, but i hope the description will help! I would really appreciate your help, I am having a hard time understanding how to solve this.
THank you :)

I visualize a right triangle, you know two sides: 4000 miles, and 17,000 miles. Solve for the hypotenuse, and subtract 4,000
hypotenuse=sqrt(4^2 + 17^2)=17,464
now subtract 4,000 miles. 
THank You! you helped a lot :)

The answer is A 13,464
