Question

determine as medidas x, y e z​

Answer 1

Resposta:

Calculando X:

16² = 8² + x²

256 = 64 + x²

256 - 64 = x²

192 = x²

$x = \sqrt{192}\\x \approx 13,86$

Calculando y:

y² = x² + 12²

y² = 13,86² + 12²

y² = 192,1 + 144

y² = 336,1

$y=\sqrt{336,1}\\y= 18,33$

Calculando Z:

y² = z² + 4²

18,33² = z² + 4²

335,99 = z² + 16

335,99 -16 = z²

319,99 = z²

$z = \sqrt{319,99}\\z \approx 17,89$
