Question

Observe a ilustração e determine o valor de x, y, z e w.

Answer 1

$x^2=1^2+1^2\\ x^2=1+1\\ x^2=2\\ x=\sqrt{2}\\\\ y^2=x^2+1^2\\ y^2=(\sqrt{2})^2+1\\ y^2=2+1\\ y^2=3\\ y=\sqrt{3}\\\\ z^2=y^2+1^2\\ z^2=(\sqrt{3})^2+1\\ z^2=3+1\\ z^2=4\\ z=\sqrt{4}\\ z=2\\\\ w^2=z^2+1^2\\ w^2=2^2+1\\ w^2=4+1\\ w^2=5\\ w=\sqrt{5}$
