Answer:
Option B is correct.
Rotation matrix =
Step-by-step explanation:
Given a vector : , rotation by radian.
A rotation matrix is a matrix that is used to perform a rotation in Euclidean space.
The standard rotation matrix is given by;
R =
Then, the matrix of rotation by radian is:
=
Then; substitute
or
or
Simplify:
Therefore, the rotation matrix of a given vector is,
Answer:

The measure of the angle x is 53.13 degrees after applying the sin ratio.
<h3>What is the trigonometric ratio?</h3>
The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
Applying sin ratio:
sinx = 12/15
sinx = 0.8
x = 53.13 degrees
Thus, the measure of the angle x is 53.13 degrees after applying the sin ratio.

Answer:
11
Step-by-step explanation:
248/24=10.3
round up to 11
The area is 25, because the length and width are both 5.
5× 5 = 25 (area)
5 + 5 + 5 + 5 = 20 (perimeter)
