What is the reference angle for 150 degrees

The reference angle is the acute angle formed between the terminal side of a given angle and the x-axis. For an angle in standard position, the reference angle is always positive and less than or equal to 90°.

For 150°, which lies in the second quadrant, the reference angle is calculated by subtracting the angle from 180°:

\[
\text{Reference angle} = 180^\circ - 150^\circ = 30^\circ
\]

So, the reference angle for 150° is **30 degrees**.
