Question

Express the angles $\frac{5{\pi }^c}{12},\frac{-7{\pi }^c}{12}$ in degrees.

Answer 1

Given angles

$\frac{5\pi }{12},\frac{-7\pi }{12}$

We know that $\pi ={180}^{\circ }$

So $\frac{5\pi }{12}=\frac{5\times {180}^{\circ }}{12}=5\times 15={75}^{\circ }\frac{-7}{12}=\frac{-7\times {180}^{\circ }}{12}=-7\times 15=-{105}^{\circ }$
