Resposta :

  • A ↔

[tex]\sf x+35^{\circ}=180[/tex]

[tex]\sf x+35-35=180-35\\\\\\\{Subtrair\:}35{\:de\:ambos\:os\:lados}\\\\\\\to \boxed{\sf x=145}[/tex]

  • B ↔

[tex]\sf x+3x+2x=180\\\\\\{Somar\:elementos\:similares:}\:x+3x+2x=6x\\\\\\6x=180\\\\\\\dfrac{6x}{6}=\dfrac{180}{6}\\\\\\\to \boxed{\sf x=30^{\sf \circ }}[/tex]
