Answer/Explanation:

12^2 = 16*x (altitude to hypotenuse theorem)

Solve for x using this equation

144 = 16x

\frac{144}{16} = x (division property of equality)

9 = x

x = 9

y^2 = 12^2 + x^2 (pythagorean theorem)

y^2 = 12^2 + 9^2 (substitution)

y^2 = 144 + 81

y^2 = 225

\sqrt{y^2} = \sqrt{225}

y = 15

z^2 = (x + 16)^2 - y^2 (pythagorean theorem)

z^2 = (9 + 16)^2 + 15^2 (substitution)

z^2 = 25^2 + 15^2

z^2 = 625 + 225

z^2 = 850

\sqrt{z^2} = \sqrt{850}

z = \sqrt{25*34}

z = 5\sqrt{34}
