Answer:
Option B is correct
the degree of rotation is, 
Step-by-step explanation:
A rotation matrix is a matrix that is used to perform a rotation in Euclidean space.
To find the degree of rotation using a standard rotation matrix i.e,

Given the matrix: 
Now, equate the given matrix with standard matrix we have;
= 
On comparing we get;
and
As,we know:

we get;

and

we get;

Therefore, the degree of rotation is, 
Answer: x= -7
Step-by-step explanation:
subtract 8x from both sides of the equation which would leave you with 2x+18=4
then you would subtract 18 from each side of the equation leaving you with 2x= -14
the divide by 2 on both sides of the equation giving you the answer of
x= -7
