The way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.
Given an incomplete sentence related to hypothesis and astronomy.
We are required to complete the sentence.
A hypothesis is basically a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon.
Astronomy is basically the study of everything in the universe beyond Earth's atmosphere.
The statement can be completed by "do experiments and observations about the prediction of the hypothesis".
Hence the way scientists know that a hypothesis in astronomy is a reasonable description of nature is to do experiments and observations about the prediction of the hypothesis.

The length of the base of the isosceles triangle is: 27 units long.
<h3>What is an isosceles Triangle?</h3>
A triangle with two equal legs and a base is called an isosceles triangle.
Thus:
Let x represent the length of each of the equal legs of the isosceles triangle.
Therefore:
The length of the base = 1 1/2(x) = 1.5x units
Perimeter = 63
Therefore:
x + x + 1.5x = 63
3.5x = 63
x = 63/3.5
x = 18
The length of the base = 1.5x units
Plug in the value of x
The length of the base = 1.5(18) = 27 units
Therefore, the length of the base of the isosceles triangle is: 27 units long.

<h3>
Who is a monopolist?</h3>
