Question

PROBLEMA 8- Ouais os valores de x e y na figura abaixo? ​

Answer 1

Resposta:

x = 15,m

y = 8m

Explicação passo a passo:

y² + 6² = 10²

y² = 100 - 36

y² = 64

y = √64

y = 8m

y +4 = 8 + 4 = 12

x² = 12² + 9²

x² = 144 + 81

x² = 225

x = √225

x = 15m

Answer 2

$\Large\boxed{\begin{array}{l}\sf no\,1^o\,tri\hat angulo\, a\,hipotenusa\,mede\,10\,m\\\sf um\,cateto\,mede\,6\,m\,e\,o\,outro\,cateto\\\sf mede\,x.\\\sf pelo\,teorema\,de \,Pit\acute agoras\,podemos\,escrever:\\\sf y^2+6^2=10^2\\\sf y^2+36=100\\\sf y^2=100-36\\\sf y^2=64\\\sf y=\sqrt{64}\\\sf y=8\,m\end{array}}$
