Work out 9/25 of 100
To do this divide 100 by 25 = 4
Then multiply 4 by the numerator : 9*4 = 36
This means 36 people didn't like the book
So if there's 100 students altogether and 36 didn't like the book,
100-36 = 64
64 people liked the book
X^2=64
X=v64
X=8 OR X=-8
2 roots
x=+8
x=-8
Solution
For this case we can conclude that B) Both angles sum 180°
Since both angles are supplementary the sum of the angles needs to be 180°
