To rotate 90 degrees given the point (x, y) the image is (y, -x)
1 is A

For 180 if the point is (x, y) then the image is (-x, -y)
2 is C

For 270 the point is (x, y) then the image is (-y, x)
3 is (-9, 5) and (-3, 4)

Answer:

X=7.9

Y=7.9

Step-by-step explanation:

We have that x=y

And form Pythagoras theorem we have

$5 \sqrt{5} = \sqrt{x ^{2} + x ^{2} } \\ take \: the \: square \: of \: the \: two \: sides \\ 125 = 2x ^{2} \\ x {}^{2} = 62.5 \\ x = 7.9$

So x = y = 7.9
