A 65 ft tree casts a 13 ft shadow. At the same time of day, how long would the shadow of a 20 ft building be? (Draw a diagram to help you set up a proportion)

Respuesta :

height of tree = 65 ft

length of shadow = 13 ft

Let draw a diagram to illustrate the question effectively

The proportion can be set up below

[tex]\begin{gathered} \frac{65}{20}=\frac{13}{x} \\ \text{cross multiply} \\ 65x=260 \\ x=\frac{260}{65} \\ x=4\text{ ft} \end{gathered}[/tex]

Th shadow will be 4 ft. do you
