Question

ayudaaaa , es urgentee !

Answer 1

Convirtiendo de radianes a grados....
$\frac{A \pi}{B}* \frac{180}{ \pi}= \frac{A*180}{B}$
Ahora la relacion sera....
$\frac{A*180}{B}=150=\ \textgreater \ \frac{A*6}{B}=5=\ \textgreater \ B= \frac{6A}{5}$
Reemp. en "P"
$P= \frac{(A+\frac{6A}{5})(A-\frac{6A}{5} )}{ A*\frac{6A}{5}}= \frac{(\frac{11A}{5})( \frac{-A}{5}) }{ \frac{6A^{2}}{5} }$
=$\frac{ \frac{-11A^{2} }{ 5^{2}}}{ \frac{6A^{2}}{5}}=$   simplificando...................
=$\frac{-11}{30}RESPUESTA INCISO "C"$
