Question

Ache o valor de X usando o teorema de pitagoras

Answer 1

x² + 20² = 25²

x² + 400 = 625

x² = 625 -400

x² = 225

x = √225

x = 15 cm ✓

Answer 2

$\large \boxed{ \begin{array}{l} a {}^{2} = b {}^{2} + c {}^{2} \\ 25 {}^{2} = 20 {}^{2} + x {}^{2} \\ 625 = 400 + x {}^{2} \\ 625 - 400 = x {}^{2} \\ 225 \: = \: x {}^{2} \\ x = \sqrt{225} \\ x = 15 \: cm\end{array}}$
