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,
check the picture below.
recall that the division is done with the dividend and divisor sorted in descending order, notice the dividend has a jump from x³ to x, so the x² is missing, but is really there, but it has a coefficient of 0, as you see there in red, so we add any missing terms on either side.
