Question

Degree measure of ${\left(\frac{7\pi }{6}\right)}^c$ is

• A. ${210}^{\circ }$
• B. ${240}^{\circ }$
• C. ${270}^{\circ }$
• D. None of these

Answer 1

The correct option is A ${210}^{\circ }$

Since $1$ radian $=\frac{180}{\pi }$ degrees
$\therefore \frac{7\pi }{6}$ radians $=\frac{7\pi }{6}\times \frac{180}{\pi }$degrees $={210}^{\circ }$
