Question

In the diagram below, a 5 foot tall girl is standing 24 feet from a lamp post at night. If her shadow from the light is 8 feet long, what is the height of the lamp post?

Answer 1

by similarity of triangles
$$\Large{
\frac{h}{24+8} = \frac{5}{8}


}$$

Answer 2

@perl
I'm confused

Answer 3

they are similar because they share that corner angle, and both have right angles.
AA similarity postulate

Answer 4

that might be a theorem now that i think about it.
