Draw Triangle: Draw a right triangle with moons A and C at the ends of the hypotenuse and the planet's center at the right angle.
Calculate Orbit Radius: Calculate the radius of the planet's orbit for the moons: 20,000km (diameter of the planet) /2+100,000km (distance above the surface) =110,000km.
Find Distance AC: Use the Pythagorean theorem to find the distance between moon A and moon C: a2+b2=c2, where c is the distance from A to C, and a and b are both equal to the radius of the orbit, 110,000 km.
Plug in Values: Plug in the values: 110,0002+110,0002=c2.
Calculate Squares: Calculate the squares: 121,000,000,000+121,000,000,000=c2.
