Trigonometric ratios are really important for engineers when they are designing buildings and bridges. These ratios help them figure out angles and distances. This is essential to make sure that structures can handle different types of stress.

Key Uses:

1. Finding Angles: Engineers use ratios like sine, cosine, and tangent to determine angles in the triangle-shaped parts of structures.
2. Spreading Weight: By looking at forces, engineers can check that weight is balanced. This is super important for safety.

Example:

Think about a triangular support beam. If you know the height ($h$) and the base ($b$), you can find the angle ($\theta$) using the tangent ratio:

$$\tan(\theta) = \frac{h}{b}$$

This knowledge helps engineers make accurate calculations, so they can build taller and safer structures. It shows just how important trigonometry is in the field of engineering!
