Answer:
[tex]3\sqrt{13}[/tex]
Step-by-step explanation:
Using the Theorem of the side of a triangle:
[tex]x^2 = 4 * (4 + 9) = 42\\x = \sqrt{42}[/tex]
And using the Height Theorem:
y = [tex]\sqrt{4 \cdot 9} = \sqrt{36} = 6[/tex]
And by the Pythagorean Therorem:
z = [tex]\sqrt{6^2 + 9^2} = \sqrt{117} = 3\sqrt{13}[/tex]
