Question

Calcule o valor de X nos triângulos retângulos abaixo:

Answer 1

Sempre será 3,4,5 mas vc pode calcular por pitagoras X^2 = 3^2 + 4 ^2 X^2 = 9 + 16 X = raiz quadrada de 25 X=5

Answer 2

$\large\text{Pelo teorema de Pit\'agoras:}~~\large\fbox{\fbox{ a^2=b^2+c^2 }}\\\\\\ Tome~a^2=x^2,~b^2=4^2,~c^2=3^2.\\\\\\x^2=4^2+3^2\\\\\\x^2=16+9\\\\\\x^2=25\\\\\\x= \sqrt{25}\\\\\\\fbox{\fbox{ x=5 }}$
