Question

06. Aplicando o teorema de Pitágoras ache o valor
do cateto que está faltando.
x
9
12​

Answer 1

x² = 9² + 12²

x² = 81 + 144

x² = 225

x = √225

x = 15 (é a hipotenusa que faltava)

Answer 2

$\large\displaystyle\sf x^2=12^2+9^2$

$\large\displaystyle\sf x^2=144+81$

$\large\displaystyle\sf x^2=225$

$\large\displaystyle\sf x=\sqrt{225}$

$\large\displaystyle\text{ \boxed{\boxed{\sf x=15}} }$
