Question

Determine as medidas x, y, z e w

Answer 1

Resposta:

Olá boa tarde.

z = 15 + 5

z = 20

y² = 15 * 20

y² = 300

y = $\sqrt{300}$

y = $\sqrt{100} *\sqrt{3}$

y = $10\sqrt{3}$

$(10\sqrt{3} )^2 = w^2 +15^2$

100 * 3 = w² + 225

w² = 300 - 225

w² = 75

w = $\sqrt{75}$

w = $\sqrt{25} *\sqrt{3}$

w = $5\sqrt{3}$

x² = 5² + $(5\sqrt{3})^2$

x² = 25 + 25*3

x² = 25 + 75

x² = 100

x = 10
