Answer:
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
MN is the diameter of the planet which is 
AM and NC are the distance of moons from the surface of the planet.

Since, angle ABC is given as 90 degree, it means, line AC will pass from the diameter of the planet.
So, distance between moon A and moon C is =



Hence the distance between point A and point C is 300000 Km. : Answer
Hope it will help :)
Undefined (not a real number)
The square root of -256 would result in an imaginary number so by terms, it's "not real". The imaginary number would be 16i. 16x 16 =256, but since it's negative, it's √16 √16i.
Answer:
2/4
Step-by-step explanation:
Change the 2 1/2 to 2 2/4
now subtract 1/4 from 2 2/4 leaving 2 1/4
Now subtract 1 3/4 from 2 1/4 in which you get 2/4
which is the answer :)
