Trigonometry is really useful for figuring out how tall buildings are! Here’s how it works:

1. Measuring Angles: First, you stand a certain distance away from the building. Then, you use a tool, like a clinometer or a protractor, to measure the angle to the top of the building.

2. Creating Triangles: This action creates a right triangle. Here’s how it looks:

   • The distance from you to the building is one side.
   • The height of the building is the side opposite to where you are standing.
   • The angle you measured is at the level of your eyes.

3. Finding the Height: By using the tangent function, you can figure out the height of the building with this formula:

$$\text{Height} = \text{Distance} \times \tan(\text{Angle})$$

It’s a great way to see how math is used in real life!
