calcular
X + Y ​

Answer 1

Respuesta:

x+y= 13+7=20

Aplicamos teorema de Pitágoras:

Hallamos x

${x}^{2} = {12}^{2} + {5}^{2}$

${x}^{2} = 144 + 25$

${x}^{2} = 169$

$x = \sqrt{169} = 13$

$x = 13$

Hallamos y

${14}^{2} = ( \sqrt{147} ) {}^{2} + {y}^{2}$

$196 = 147 + {y}^{2}$

$49 = {y}^{2}$

$\sqrt{49} = y$

$y = 7$
