Question

Find the degree measure of ${\frac{\pi }{8}}^c$

Answer 1

We have ${\pi }^c={180}^{\circ }$

$\therefore 1^c={\frac{180}{\pi }}^{\circ }$

${\frac{\pi }{8}}^c={(\frac{\pi }{8}\times \frac{180}{\pi })}^{\circ }={\left(22\frac{1}{2}\right)}^{\circ }={22}^{\circ }\times \frac{1}{2}\times {60}^{\circ }={22}^{\circ }{30}^{\prime }$
