180 - 103 = 77 ( we need to find w and since 103 is supplementary angles with angle w they equal to 180) !! THE WHOLE TRIANGLE MUST EQUAL TO 180 !! now we have two of the interior angles, we need to add them and subtract it with 180. 77 + 87 = 167 ( we are adding angles x and w) 180 - 167 = 16 ( we are subtracting the total and the sum of the angles x and w)
THE MEASURE OF ANGLE Y IS 16 degrees!! hope this helps
There are billions of galaxies in the universe, not just one.
The universe formed from a central point.
Most galaxies in the universe are moving away from Earth.
Explanation:
Hubble's theory is a model of the observable universe and represents the earliest form of evolution of the universe in the form of a big bang. The process of large-scale evolution and origin and growth of the universe.
It explains the development of the universe from an ingle bang where all the galaxies spread and are still growing further apart from each other.
It explains the formation of the university from a single point in the history of time. It also explains the formation of galaxies in the universe such as those of the spiral and elliptical ones. How the galaxies and planets came into the formation from this one single point.
