The answer is definitely B
Hi, glad to help u.
so, complimentary angles means two adjacent angles measured as a right angle which means two angles measured as 90 degrees!
So 7x-3 and x+13 is a pair of complimentary angles.
Then we can know(
(7x-3)+(x+13)=90
8x+10=90
x=10
so 7x-3=67
x+13=23
hope that helps u
The majority of the scientists believe that the humans are responsible in big portion of the global warming . The main reasons for this are the changes in the atmosphere because of the human activities, as well as the correspondence of the rise of the global temperatures with the development of the industry. Taking all things into account, it seems that the humans have effect on the global climate, and because of the enormous amount of greenhouse gasses that are released into the atmosphere, the temperatures are gradually rising. On the other hand, the global warming is also a natural process, so the major factors are still natural, not the human activity as it is often propagated, but the human activities are small portion that adds on the natural process. Evidence about this are the geologic records which show that the climate has been warming up naturally numerous times, the melting of the ice sheets are also good evidence about the warming of the climate, as well as the changing patterns of the climate across the globe.
I believe that the correct answer to this question would be "produced with the help of <span>ecosystem-based management". Books are often made out of trees, and in order to produce paper, ecosystem-based management is needed.</span>
