<u>Answer in picture.</u>
Answer/Step-by-step explanation:
When the scale factor of a dilation is less than one, the dilation is a reduction. Corresponding sides in similar figures must be proportional. Dilations of an angle are congruent to the original angle. Dilation (scaling) does not affect angle measure. It remains the same. That is, an image of an angle transformed by scaling is an angle of the same measure as an original.
Dilations always increase the length of line segments. If a shape is dilated, the angles remain the same. Dilations increase the measure of angles in a shape. Dilations of a triangle are similar to the original triangle.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Dilation is the increase or decrease in size of an object by a factor k. If k > 1, it is an enlargement but if k < 1, it is a decrease. Dilation preserves the orientation of an object but changes the size.

Using the mid-point concept, it is found that point B is located at coordinates (-6.5, 0).
<h3>What is the midpoint concept?</h3>The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
The center is the midpoint of the two coordinates of the diameter, hence:
For the x-coordinate:
x + 0.5 = -6
x = -6.5
For the y-coordinate:
y + 6 = 6
y = 0

The angle of rotation of triangle ABC to A'B'C is 105°
<h3>How to illustrate the information?</h3>It should be noted that the rotation from ABC to A'B'C is in a clockwise direction.
Point B is also on the x axis and point B' is in the second quadrant.
In this case, the angle that depicts the second quadrant is 105°.
In conclusion, the correct option is D.
The complete question is:
