Question

Hello! Thank you for helping me today, I need a little bit of assistance to understand the rest of this question please. (This is is not an active test, it is a book I am studying in order to take the ASVAB in a couple of weeks.)

Answer 1

Solution.

Let the height of the tree be h

`\begin{gathered} Using\text{ the idea of similar triangle,} \\ (4)/(9)=(h)/(9+12) \end{gathered}`
`\begin{gathered} (4)/(9)=(h)/(21) \\ h=\frac{21\text{ x }4}{9} \\ h=(28)/(3) \\ h=9(1)/(3)\text{ ft} \end{gathered}`
`The\text{ height of the tree is 9 }(1)/(3)\text{ ft}`

The correct option is C
