Answer 1

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
$\frac{1}{y} =\frac{y}{8}$
Cross multiply and you get:
$8=y^{2}$
$2\sqrt{2} = y$

Now that we have y, we can solve for z. We can do that using the pythagoream theorem.
$a^2+b^2=c^2$
$(2\sqrt{2})^2 + 8^2 = z^2$
$8+64=z^2$
$72 = z^2$
$6\sqrt{2} = z$

So z is 6 radical 2

Answer 2

8+1
9 times y
9y is the answer
