Question

Em um triangulo equilatero as medidas dos seua lados sao respecrivamente x+4, 4× -2 e y. Sendo assim, qual o valor de x e y nesse triangulo? a) x= 3, y= 5 b) x= 2, y=6 c) x= 5, y= 8 c) x= 10, y= 14​

Answer 1

$\mathsf{4x-2=x+4}\\\mathsf{4x-x=4+2}\\\mathsf{3x=6}\\\mathsf{x=\dfrac{6}{3}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{x=2}}}}}$

$\mathsf{y=x+4}\\\mathsf{y=2+4}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{y=6}}}}}$

$\huge\boxed{\boxed{\boxed{\boxed{\mathsf{\maltese~~alternativa~~b}}}}}$
