Step-by-step explanation:
To convert an angle from degrees to radians multiply the value by [tex] \frac{\pi}{180} [/tex]
From the question the value to be converted is - 420°
The value in radians is
[tex] - 420 \times \frac{\pi}{180} \\ = - \frac{420\pi}{180} [/tex]
Reduce the fraction with 60
We have the final answer as
[tex] - \frac{7\pi}{3} [/tex]
