First, to find z, we must first find y. Since y is the altitude, we can use triangle altitude theorem to solve that.

ie. altitude/left side = right side/altitude

(1)/(y) =(y)/(8)
Cross multiply and you get:

8=y^(2)

2√(2) = y

Now that we have y, we can solve for z. We can do that using the pythagoream theorem.

a^2+b^2=c^2

(2√(2))^2 + 8^2 = z^2

8+64=z^2

72 = z^2

6√(2) = z

So z is 6 radical 2
