A sequence of transformations is described below.
A rotation about a point PPP
A translation
A reflection over a line \overleftrightarrow{QR}
QR

Q, R, with, \overleftrightarrow, on top
Another translation
Which of the following must be preserved under this sequence of transformations?
Choose 1
Choose 1

(Choice A)
A
Angle measures only

(Choice B)
B
Segment lengths only

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
