Answer 2

Basta utilizarmos uma regra de tres.

Sabemos que 1π radianos equivale a 180°, logo:

$1\pi~radianos~_{-----}~180^\circ\\\frac{5\pi}{3}~radianos~_{-----}~x\\\\\\Multiplicando~Cruzado\\\\\\x~.~1\pi~=~\frac{5\pi}{3}~.~180\\\\\\x~.~1\pi~=~\frac{5\pi~.~180}{3}\\\\\\x~=~\frac{5\pi~.~180}{3~.~1\pi}\\\\\\x~=~\frac{5\pi\!\!\!\backslash~.~180\!\!\!\!\!\backslash}{3\!\!\!\backslash~.~1\pi\!\!\!\backslash}\\\\\\x~=~\frac{5~.~60}{1~.~1}\\\\\\\boxed{x~=~300^\circ}$
