Subtract the sum of the two angles from 180 degrees.
Answer: Maybe a
Step-by-step explanation:
I mean it is confusing but still look over it
D){x+8y=369{y=8x D is the answer
Reflection over the y-axis:
(x, y) ⇒ (-x, y)
Reflection of that over the line y = x:
(-x, y) ⇒ (y, -x)
Rotation counterclockwise by 270°:
(x, y) ⇒ (y, -x) . . . . . . equivalent to reflection over y, then over y=x.
The appropriate choice is ...
C) Reflecting over the y-axis and then reflecting over the line y = x.
