Answer: z =
√(10)

Explanation:

To find z, you must set up a proportion to solve.

To find the altitude of a special right triangle, the formula is:


(a)/(x) =(x)/(b)

You can use 5 as a and 2 as b to complete the proportion:


(5)/(x) =(x)/(2)

Next, to solve:

Step 1: Cross-multiply.


(5)/(z) =(z)/(2)

(5)*(2) = z*z

10 = z²

Step 2: Take square root.

10 = z²

√10 = z

I hope this helps!
