Respuesta :

j/6=31/28  because of similar triangles....

j=6.64ft

Answer:  Option 'A' is correct.

Explanation:

Since we have given that

Length of Julian's shadow = 6 feet

Height of tall building = 31 feet

Length of shadow of building = 28 feet

Let Height of Julian be x

Since there is direct variation between height and shadow,so

Required proportion will be

[tex]\frac{x}{6}=\frac{31}{28}[/tex]

Now, we'll calculate the value of x i.e. height of Julian,

[tex]x=\frac{31\times 6}{28}=6.64\ feet.[/tex]

Hence, Option 'A' is correct.
