A tall tree casts a shadow that is 30 meter long. At the same time, Nikki is 2 meters tall and casts a 3 meter shadow. How tall is the

tree?

We can set up a proportion to solve for the height of the tree:

height of tree / length of tree's shadow = height of Nikki / length of Nikki's shadow

Let x be the height of the tree. Then the proportion becomes:

x / 30 = 2 / 3

Cross-multiplying, we get:

3x = 60

Dividing both sides by 3, we get:

x = 20

Therefore, the height of the tree is 20 meters.

To find out how tall the tree is, we can set up a proportion using the measurements of Nikki and her shadow.

Let's represent the height of the tree as "x".

The proportion can be set up as follows:

Height of Nikki / Length of Nikki's shadow = Height of the tree / Length of the tree's shadow

Plugging in the given values, we have:

2 meters / 3 meters = x meters / 30 meters

Now let's solve for x by cross-multiplying:

2 meters * 30 meters = 3 meters * x meters

60 meters = 3x meters

Divide both sides of the equation by 3 to solve for x:

60 meters / 3 = x meters

x = 20 meters

Therefore, the tree is 20 meters tall.
