Question 1 is 87 because two smaller angles added together equals the bigger angle.

question 2 is x=8. the equation is 3x-4+6x+2=70 and then solve for x.

question 3 is x=7. the equation is 6x-2+15=7x+6 and then solve for x.

question 4 is 21 because an angle bisector splits and angle into two equivalent angles.

question 5 is x=7. the equation would be 62=2(4x+3) and then solve for x.

If carbon dioxide (CO₂) was much more abundant in Earth's early atmosphere, what happened to most of this gas?
frutty [35]

Answer:

The early atmosphere was comprised of a high amount of carbon dioxide and water vapor. These water vapors have undergone the process of condensation and resulted in the formation of oceans. The carbon dioxide gas was mostly consumed by primitive lives such as the blue-green algae, and cyanobacteria, and by carrying out the process of photosynthesis, it liberated oxygen.

Some amount of carbon dioxide was also brought down from the atmosphere by mixing up with the rainwater (acid rain), and are mostly concentrated in the deeper zone of the oceans forming limestones.

Currently, a total of about 0.03% of CO₂ is present in the atmosphere in today's world.
