Trigonometric ratios, which include sine, cosine, and tangent, are super helpful for finding heights and distances. Here's how they work:

1. Finding Height: If you want to know how tall a tree is, you can measure how far you are from the tree and the angle you look up to see the top.

   If you're ( d ) meters away and the angle is ( \theta ), you can find the height ( h ) using this formula:

   $h = d \cdot \tan(\theta)$

2. Measuring Distance: If you want to know how far away a tower is, you can measure the angle you look down from the top.

These methods help us get accurate measurements in areas like engineering and physics!
