Given the angle:
253 degrees
Let's find the reference angle to the given angle for a rotation.
The given angle, 253 degrees, is in quadrant 3.
To find the reference angle of ang angle in quadrant 3, we have:
[tex]\theta_{ref}=\theta-180[/tex]Hence, we have:
[tex]\begin{gathered} \theta_{ref}=253-180 \\ \\ \theta_{ref}=73^o \end{gathered}[/tex]Therefore, the reference angle is 73 degrees.
ANSWER:
73°
