Answer:
275,000
Step-by-step explanation:
Diametre of the planet = 45,000
Each moon is 115,000 away from the planet (represented by A, B, and C
Moons A, B, and C form a right triangle.
AC form the hypotenuse.
So, take the distance from the Planet to moon C (115,000) add it the distance from the Planet to Moon A (115,000) and add the diametre of the planet (45,000) to get the answer 275,000
2(115,000) + 45,000 = 275,000
