this is supposed to be Law of Sines and Law of Cosines (round to 1 decimal)

Assume that the earth is a sphere of radius 3980 miles. A satellite travels in a circular orbit around the earth, 900 miles above the earth's surface, making one full orbit every 6 hours. If it passes directly over a tracking station at 2 pm, what is the distance from the satellite to the tracking station at 2:05 pm?

I have no clue what to do so I first found the Circumference of the satellite which was 30,661.9miles, I divided that by 6 to find distance in 1 hour which was 5110.3miles, then divided that by 60 to find distance in minutes which was 85.2miles. Multiplied that by 5 to get 425.9miles because the satellite moved 5 minutes over the tracking station. Now I have a triangle say point A to point B is 900miles, point B to C is 425.9miles, what is the length of point C to A?......

WOW typing this out I realized I can just use pythagorean theorem to find the distance. I feel stupid lol. Well if anyone wants to check my answer for me that would be cool my answer is 995.7miles. Thanks
