Question

As medidas 2x e 4x são aberturas de ângulos e as duas aberturas são dadas como ângulos complementares. Quais são os ângulos?

Answer 1

$\Large\boxed{\begin{array}{l}\boldsymbol{Dois\,\hat angulos\,s\tilde ao\,complementares}\\\boldsymbol{quando\,sua\,soma\,resulta}\\\boldsymbol{em\,90^\circ}\\\sf2x+4x=90^\circ\\\sf 6x=90^\circ\\\sf x=\dfrac{90^\circ}{6}\\\\\sf x=15^\circ\\\sf 2x=2\cdot15^\circ=30^\circ\\\sf 4x=4\cdot15^\circ=60^\circ\\\sf os\,\hat angulos\,procurados\,s\tilde ao\,30^\circ\,e\,\,60^\circ\end{array}}$
