Explicação passo a passo:

[tex]\Large \text{$\sf x + 30^{\circ} = 70^{\circ}$}[/tex]

[tex]\Large \text{$\sf x = 70^{\circ} - 30^{\circ}$}[/tex]

[tex]\Large \boxed{\boxed{\text{$\sf x = 40^{\circ}$}}}[/tex]

[tex]\Large \text{$\sf 2y + 20^{\circ} = 110^{\circ}$}[/tex]

[tex]\Large \text{$\sf 2y = 110^{\circ} - 20^{\circ}$}[/tex]

[tex]\Large \text{$\sf 2y = 90^{\circ}$}[/tex]

[tex]\Large \boxed{\boxed{\text{$\sf x = 45^{\circ}$}}}[/tex]
