Con todo procedimiento porfavor​

Answer 1

Explicación paso a paso:

Recuerda:

${360}^{o} = {400}^{g} = 2\pi \\ {180}^{o} = {200}^{g} = \pi$

Por tanto:

$\frac{\pi}{2} = \frac{\pi}{2} \times \frac{ {180}^{o} }{\pi} = \frac{ {180}^{o} }{2} = {90}^{o}$

${10}^{g} \times \frac{ {180}^{o} }{ {200}^{g}} = {9}^{o}$

Reemplazando:

$\frac{ {90}^{o} + {60}^{o}}{ {9}^{o}} = \frac{ {150}^{o} }{ {9}^{o} } = \frac{ {50}^{o} }{ {3}^{o} }$
