(0,4) (0,-2) (-2,0)
for the reflection over the x-axis, all the y values go to their opposite (0,-4) (0,2) (2,0)
then at the rotation it goes (-x,-y) and becomes (0,4) (0,-2) (-2,0)

Answer:
A. 56.54867 rounded to 56.56
Step-by-step explanation:
18/2=9
r=9
C=2πr=2·π·
C=2(3.14)(9)
9≈56.54867
So if it is a parallelogram then the angles will add up to 360° and the angles opposite one another will be equal
we can start by finding y
3y = 42
divide by 3
y = 14
now we know that both angles are equal to 42° so to find the missing angles we must double 42 and subtract is from 360 then divide by 2 to find the individual angle
42 x 2 = 84
360 - 84= 276
276/2 = 138
the angle of 8x - 6 = 138
now we solve for x by first adding 6
8x = 144
then divide by 8
x = 18
so y = 14 and x = 18
