Explanation:
B is the vertex angle of isosceles triangle. So AB = BC and base side is AC.
As AB = BC
So,

The correct answer is - Amazon Basin.
The northern half of Brazil is dominated by the Amazon Basin. This basin is formed by one of the longest rivers in the world, the Amazon River, which is also the river that has the highest amount of water in it. It lies in the middle of the Amazon Basin, cutting it in half, and in certain parts of the year flooding parts of it. This basin is covered by tropical rainforest, in fact the largest tropical rainforest in the world, the Amazon rainforest. It is an area dominated by lowlands and small hills, cut by thousands of smaller and larger rivers, all of which are tributaries to the largest one, the Amazon River. This basin is also the place on the planet that has the highest biodiversity in the world of plants or animals.

Answer: The greater the distance to a galaxy, the greater its redshift</h2>
When we talk about the <u>visible electromagnetic spectrum</u>, we know it starts in violet-blue and ends in red.
Now, in this context the astronomer Edwin Powell Hubble observed several celestial bodies, and when obtaining the spectra of distant galaxies he observed the spectral lines were displaced towards the <u>red</u><u> </u>(red shift), whereas the nearby stars showed a spectrum displaced to the <u>blue</u>.
From there, Hubble deduced that the farther the galaxy is, the more redshifted it is in its spectrum, and noted that all galaxies are <em>"moving away from each other with a speed that increases with distance"</em>, and enunciated the now called<u> Hubble–Lemaître Law</u>.
This means in the past the distance between two galaxies was smaller than at present, being this the proof that <u>the universe is expanding</u> (like a balloon expands when it is filled with air or another gas).
At this poitn it is important to stay clear that <u>the redshift is not produced by the relative movement of the galaxies with each other</u>. This effect is in fact, due to the <u>own expansion of the space</u> among the galaxies.
South America is the world leader in Hydroelectric power. Hope this helps
