Apentagon is transformed according to the rule r0, 180°. which is another way to state the transformation?
a (x, y) → (–x, –y)
b (x, y) → (–y –x)
c (x, y) → (x, –y)
d (x, y) → (–x, y)

A. (x,y) > (-x,-y)

Explanation:

R0 means that the rotation is about the origin point

Therefore, (R0,180) would mean that we are rotating the figure 180° about the origin

This rotation implies the following:

x-coordinate of the image has the same value but opposite sign as the x-coordinate of the original picture > x' = -x

y-coordinate of the image has the same value but opposite sign as the y-coordinate of the original picture > y' = -y

Combining the above statements, we would reach the following:

(x,y) > (-x,-y)

Examples:

(1,2) > Rotation (R0,180) > (-1,-2)

(-1,2) > Rotation (R0,180) > (1,-2)

(1,-2) > Rotation (R0,180) > (-1,2)

(-1,-2) > Rotation (R0,180) > (1,2)

Hope this helps :)

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
