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:
![\theta_(ref)=\theta-180](https://img.qammunity.org/2023/formulas/mathematics/high-school/ja2q8g24eapxwhqmzeqbwrvv3f1201w28c.png)
Hence, we have:
![\begin{gathered} \theta_(ref)=253-180 \\ \\ \theta_(ref)=73^o \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/89vby1477o9ov59h0x7ryg9wsokv0fk8sn.png)
Therefore, the reference angle is 73 degrees.
ANSWER:
73°
