C. Do not contain enough oxygen to support plant and marine life
Explanation:
The mean angle is all the angles added up together then divided by how many angles they were. For example:
I have four angles 44°, 37°, 29° and 67°, what I would do is add them all up together, i.e, 44+37+29+67, which equals to 180. Then I would divide 180 by how many angles they were, so I would do 180÷4 which equals to 45. So the mean angle would be 45°, that's how you find the mean, hope that helps.
Answer:
The stars mass (once it becomes a star) is inversely proportional to its lifetime as a main sequence star. A red dwarf can survive for many billions of years; a star that has twice the mass of the Sun, such as Sirius A, will have 25% of the Suns lifetime.
Hope this helps :)
