Question

Determine o valor de x e y

Answer 1

$\mathsf{5X-60^{\circ}=x+20^{\circ}}\\\mathsf{5x-x=20^{\circ}+60^{\circ}}\\\mathsf{4x=80^{\circ}}\\\mathsf{x=\dfrac{80^{\circ}}{4}}$

$\boxed{\boxed{\mathsf{x=20^{\circ}}}}$

$\mathsf{x+20=20^{\circ}+20^{\circ}=40^{\circ}}$

$\mathsf{y=180^{\circ}-40^{\circ}=140^{\circ}}$
