Hello,
Answer A is the only finite set.
Astronomers deal with objects in space, so it's most likely they would use geometry to determine how far they are, how big they are, etc.
Have a nice day! :)

Answer: 2.19 pounds
Step-by-step explanation:
35 / 16 is 2.1875, if you round that you get 2.19
Answer:
The height is 4.472
Step-by-step explanation:
That formula is Heron's formula.
Where "s" is calculated like this:
s = (a + b + c) / 2
In this case:
a = 14
b = 12
c = 6
replacing:
s = (14 + 12 + 6) / 2
s = 16
Now we calculate the area:
A ^ 2 = 16 * (16−14) * (16−12) * (16−6)
A ^ 2 = 1280
A = 35.777
The area of the triangle is:
A = b * h / 2
In this case we will take the base as the longest side of the triangle, that is to say = 14
Thus:
h = A * 2 / b
h = 35.777 * 2/16
h = 4.472
So the height is 4.472
