Question

encuentra los valores de x y de z ​

Answer 1

Respuesta:

x=15

z=12.5

Explicación paso a paso:

Utilizamos pitagoras

$c {}^{2} =a {}^{2} + b {}^{2}$

triangulo grande

$d {}^{2} - c {}^{2} = a {}^{2}$

$a = \sqrt{25 {}^{2} - 20 {}^{2} }$

$a = \sqrt{625 - 400}$

$a = \sqrt{225} = 15 = x$

triangulo pequeño

$z = \sqrt{7.5 {}^{2} + 10 {}^{2} }$

$z = \sqrt{56.25 + 100}$

$z = \sqrt{156.25} = 12.5$
