Thread: what would i use to solve this problem

1. what would i use to solve this problem

A tree casts a 25 foot shadow. At the same time of day, a 6 foot man standing near the tree casts a 9 foot shadow. What is the approximate height of the tree to the nearest foot?

i kind of need help solving this problem. would i use the pythagorean theorem to solve this problem?

use proportions between similar right triangles ...

let $h$ = height of the tree

$
\frac{h}{25} = \frac{6}{9}
$

determine the value of $h$

You can along with trigonometry and geometry with similar triangles.
