To solve this problem, we can use the concept of similar triangles. The ratio of the height of the girl to her shadow is the same as the ratio of the height of the tree to its shadow. So, we can set up a proportion:

( \frac{1.2}{2} = \frac{x}{75} )

Solving for (x), the height of the tree:

( x = \frac{1.2 \times 75}{2} = 37.5 ) meters tall.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
