Question

na A figura a seguir AB //De. determine as medidas X e Y ​

Answer 1

Resposta:

x=7 e y=24

Explicação passo-a-passo:

$\frac{8}{12}=\frac{x}{21}=\frac{16}{y}\\\frac{8^{:4}}{12^{:4}}=\frac{x}{21}\\\frac{2}{3^{:3}}}=\frac{x}{21^{:3}}\\1=\frac{x}{7}\\x=7\\\\agora\\\frac{1}{12}=\frac{2}{y}\\y=24$
