Question

Determine o valor de x e y nas figuras sabendo q u r e s são paralelas

Answer 1

$\large\boxed{\begin{array}{l}\rm x=50^\circ~(\hat angulos\,correspondentes)\\\rm x+y=180^\circ~(\hat angulos\,colaterais\,internos)\\\rm 50^\circ+y=180^\circ\\\rm y=180^\circ-50^\circ\\\rm y=130^\circ\end{array}}$
