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

`(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

Answer 2

8+1
9 times y
9y is the answer
