What are the new coordinates of the figure above if it is rotated 180° clockwise about the origin? A. (3,3), B'(-3,7), C'(3,7)

B. (-3,3), B'(-7,3), C'(-7,-3)

C. (-3,3), B'(-7,3), C'(7,-3)

D. (3,3), B'(3,7), C'(-3,7)

Step-by-step explanation:

A'(3,3), B'(3,7), C'(-3,7) (for you D)

Step-by-step explanation:

Multiply each coordinate by -1

Had the same question and saw you needed help :)

a. is correct

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
