Answer:
8.4
Step-by-step explanation:
Hello!
The x and y are 'swapped. so we have
a reflection over the line y=x
The complete question in the attached figure
we have that
250°----------> belong to the third quadrant
if 2pi radians-------------> 360°
X-------------------------> 250°
X=250*2pi/360------------> 1.39 pi radians
then
<span>the radian measure of the central angle is 1.39pi
</span>
hence
the answer is
the option C) pi to 1.39pi radians
