Answer:

Galaxies are sprawling systems of dust, gas, dark matter, and anywhere from a million to a trillion stars that are held unitedly by gravity. Nearly all large galaxies are believed to also contain supermassive black holes at their centers. In our galaxy, the Milky Way, the sun is just one of about 100 to 400 billion stars that spin around Sagittarius A, a supermassive black hole that holds as much mass as four million suns. Some of the galaxies receding from the Milky Way are ellipsoidal, like footballs. Galaxies can also be thin and flat with tentacle-like arms.

Jack and Andrea want to create a right triangle together using values of sand y and the polynomial identity to generate
koban [17]

Answer:

A right triangle can be considered as a special type because the relationship of its sides can be described using the hypotenuse formula: c^2 = a^2 + b^2 or c^2 = x^2 + y^2 where, c is the hypotenuse of the triangle and is the side opposite to the 90° angle while a and b are the sides adjacent to the 90° angle.

In the problem statement, we are given that one of the side has a measure of 2 = x, while the hypotenuse is 5 = c, therefore calculating for y: y^2 = c^2 – x^2 y^2 = 5^2 – 2^2 y^2 = 21 y = 4.58

Explanation:

The natural number is the number before the decimal. Therefore the answer is: y = 4

It is may 5 and you are somewhere in the northern hemisphere if you determine that the noon sun is 51 above your southern horizo
Ne4ueva [31]

Answer:

The latitude of my location is 62°

Explanation:

As per the relationship between the height of sun above horizon and the latitude, we have:

h = 113 - Lat

Inserting the given value of height which is 51 degrees, we get

Lat = 113 - 51 = 62^o

Therefore the latitude of the location is 62 degrees north.
