Answer: z = 
Step-by-step explanation:
To find <em>z</em>, you must set up a proportion to solve.
To find the altitude of a special right triangle, the formula is:

You can use <em>5</em> as <em>a</em> and <em>2</em> as <em>b</em> to complete the proportion:

Next, to solve:
<u>Step 1</u>: Cross-multiply.

(5)*(2) = z*z
10 = z²
<u>Step 2</u>: Take square root.
10 = z²
√10 = z
