the problem with this study is the fact that they used precise numbers
hope i helped:)
This is the theory of algebra, to simply the expression we proceed as follows;
[sqrt(x-2)+5/sqrt(x-2)]/(x-2)
simplifying the numerator we get:
sqrt(x-2)+5/sqrt(x-2)
=[x-2+5]/sqrt(x-2)
=(x+3)/sqrt(x-2)
therefore our entire expression will be:
[(x+3)/sqrt(x-2)]/(x-2)
[(x+3)/(x-2)^(1/2)]*1/(x-2)
applying the law if indices we get
=(x+3)/(x-2)^(3/2)
Answer:
The one opposite of 100°, as the bigger the angle, the bigger the opposing side, is the biggest.
By the same logic, the one opposite 45° is the next biggest.
Continuing with that, the one opposite the black one (which would equal 35°, I think) is the smallest.
Perimeter is the boundary/outline/ surrounding
For example if you measure around your house that would be the perimeter.
Area is the size of something.
Like if you wanted to know the amount of space in a box.
