We have to express -340° in radians.
We first have to express it as a positive angle.
As 0° = 360°, we can express an equivalent angle as:
![-340\degree=360\degree-340\degree=20\degree](https://img.qammunity.org/2023/formulas/mathematics/high-school/qp5s9iqnnlnwlxhxci2qahxfoqxkuc5u8m.png)
We now use the equivalency between radians and degrees, where π rad = 180° and express the angle as:
![20\degree\cdot\frac{\pi\text{ }rad}{180\degree}=(20)/(180)\pi\text{ rad}=(\pi)/(9)\text{ rad}](https://img.qammunity.org/2023/formulas/mathematics/high-school/qzscch0e26f8vqxqywfewyrp82b9wyee9h.png)
Answer: the equivalent angle in radians is π/9 rad.
