The shadow of a 1 m high pole thrown on a horizontal plane is 0.8 m long. At the same time, the shadow of a tree thrown on a horizontal plane is 6.4 m. Determine the height of the tree.

Correct answer:

x =  8 m

Step-by-step explanation:

$$\begin{gathered} 1\mathrm{/}0.8=x\mathrm{/}6.4 \\ 0.15625x=1.25 \\ x=8\text{ m} \end{gathered}$$
