Answer:
2(8x^2-13x+10)
Explanation:
There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.
Let's let A represent the measurement of one of the those angles in our pentagon.
The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.
But we are also given that this equals 40x^2-65x+50.
So that means 5A=40x^2-65x+50.
If we divide both sides by 5 we can find what one of our angles is in terms of x. So let's do that A=8x^2-13x+10.
So we want to know the sum of two our angles, we want to know what is A+A or 2A. 2A=2(8x^2-13x+10). To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

There not the same because the tilt of the earth axis is 22 degrees.The sun is directly overhead at either one of the tropics of Cancer or Capricorn every six months giving high temps in these regions.If there wasn't any tilt in the earth axis there will be no season's.
The answer is cow pasture.
When the dead cow pasture decomposes, it releases phosphates into the environment. In addition, the cows that feed on the pasture release manure with phosphates content. When the phosphates reach the pond, they spur up bacteria and algal growth in the pond causing an algal bloom. This results in taking up of dissolved oxygen (for cellular respiration) until the waters become anoxic.
