Question

Please help me with this....

Answer 1

Answer:

$3\sqrt{13}$

Step-by-step explanation:

Using the Theorem of the side of a triangle:

$x^2 = 4 * (4 + 9) = 42\\x = \sqrt{42}$

And using the Height Theorem:

y = $\sqrt{4 \cdot 9} = \sqrt{36} = 6$

And by the Pythagorean Therorem:

z = $\sqrt{6^2 + 9^2} = \sqrt{117} = 3\sqrt{13}$
