Question

Calcule a medida do X no triângulo a seguir:​

Answer 1

$\large \sf{x = 35 }$

Explicação:

$\large \text{ \sf{ x {}^{2} = 21 {}^{2} + 28 {}^{2} } }$

$\large \text{ \sf{x {}^{2} = 441 + 784} }$

$\large \text{ \sf{x {}^{2} = 1225 } }$

$\large \text{ \sf{x = \sqrt{1225} } }$

$\large \sf{x = 35 }$

Answer 2

$\large\boxed{\begin{array}{l} \tt x {}^{2} = 28 {}^{2} + 21 {}^{2} \\ \tt x {}^{2} = 784 + 441 \\ \tt x {}^{2} = 1225 \\ \tt x = \sqrt{1225} \\ \tt x = 35\end{array}}$
