Answer with explanation:

Vertices of Triangle X Y Z →→ Pre-Image : X(3,-6),Y(1,-2),Z(-1,-5)

Vertices of Triangle X' Y' Z' →→ Image : X'(-3,6),Y'(-1,2),Z'(1,5)

→→Drawing the Triangle XYZ and X'Y'Z' on coordinate plane

→All sides are unequal in length, so it is a Scalene Triangle.

Joining Z and Z'

⇒And ,finding that , if we rotate Triangle X Y Z in Anti clockwise Direction  by an angle of 180°, it gives Triangle X'Y'Z'.

Option :Anti Clockwise Rotation by an angle of 180°

Answer:

180° rotation about the origin

Step-by-step explanation:

Analysing triangles XYZ and X'Y'Z' it can be seen that coordinates of point X (3, -6) were changed to (-3,  6), that is, (x, y) were changed to (-x, -y). The relation between Y and Y', and between Z and Z' is the same. A 180° rotation about the origin translates point (x, y) to point (-x, -y). In a 180° rotation, clockwise or counterclockwise rotation doesn't make any difference.

What is the approximate value of point Y?<br><br> second picture is the answer's
Doss [256]
<h2>Hello!</h2>

The answer is: A. 2π

<h2>Why?</h2>

First,  in order to make it easier, let's convert the numbers into entire or decimal numbers.

A=2\pi=6.28\\B=2\sqrt{12}=6.92\\C=\sqrt{8}=2.82\\D=5.4

So, ordering it:

C, D, A, B

W=C=2.82\\X=D=5.4\\Y=A=6.28\\Z=B=6.92

So, Y=A=6.28

Have a nice day!
