Answer:
Pre-dusk, early to medium twilight phases allow outdoor activities without using artificial lighting
Explanation:
Civil twilight is a term, and we describe it as "the time after sunset and before sunrise ends or begins when the sun seems to be about 6 degrees underneath the horizon during which the light for normal outdoor occupations is adequate on clear days.
Nautical twilight is the second stage of twilight. By this time, both horizon and the brighter stars are easily visible, making navigation around sea possible.
Astronomical twilight occurs whenever the Sun is under the horizon between 12° and 18°
Pre-dusk, early to medium twilight phases allow outdoor activities without using artificial lighting
According to dollar democracy on steroids, the intergovernmental panel on climate change (IPCC) report on global warming, released in October 2018, says that <u>fundamental human rights are guaranteed to all.</u>
<u></u>
Global warming is the long-term warming of the earth's surface caused by human activities, mainly due to the burning of fossil fuels, since before the Industrial Revolution (1850 to 1900). Raise it. This term is incompatible with the term "climate change".
Potential future impacts of global climate change include more frequent wildfires, longer droughts in some areas, periods of tropical storms, and increased intensity.
Climate change is an aspect of climate change and refers to the long-term rise in global temperature. This is mainly caused by rising levels of greenhouse gases in the atmosphere due to human activities such as burning fossil fuels and agriculture.

<h3>As we know that sum of three angles of triangle is 180º.</h3>
we have
![angle \: a + angle \: b+ angle \: c= 180 \\](https://tex.z-dn.net/?f=%20angle%20%5C%3A%20a%20%2B%20angle%20%5C%3A%20b%2B%20angle%20%5C%3A%20c%3D%20180%20%5C%5C%20)
![a + 45 + 90 = 180 \\ a = 180 - 135 \\ a = 45](https://tex.z-dn.net/?f=a%20%2B%2045%20%2B%2090%20%3D%20180%20%5C%5C%20a%20%3D%20180%20-%20135%20%5C%5C%20a%20%3D%2045)
<h3>
![\blue\star](https://tex.z-dn.net/?f=%5Cblue%5Cstar)
The angles a and c are equal so,</h3>
- cb = ab. [ sides opp to equal angles are equal]
so x is also 16
<h3>
![\blue\star](https://tex.z-dn.net/?f=%5Cblue%5Cstar)
Now we have two side we can easily find the third side by P.G.T</h3>
<h3>so the r is root 512 and x is 16.</h3>
Hope it helpa
Answer:
X=52
x=17 over 2 and negitive 7 over 2
