Amelia is 5

Question

feet tall and casts a 4
-foot shadow.
A tree next to her casts a 12
-foot shadow.
The two triangles formed are similar because the angle to the sun is the same.

Choose two equations that can be used to find the height, h
, of the tree.

A girl with height 5 feet and shadow length 4 feet. A tree with height h feet and shadow length 12 feet.
CLEAR CHECK

5−4=12−h

412=h5

5h=4⋅12

124=h5

54=h12

54=12h

Answer 1

The two equations that can be used to find the height of the tree are:

1. 5/h = 4/12
2. 5h = 4*12
