Questions & Answers

Q: How is trigonometry used in real life?

Trigonometry is used in various real-life applications, such as architecture, engineering, and navigation. It helps determine distances, heights, angles, and more.

Q: What is the importance of forming a right triangle in trigonometry problems?

Forming a right triangle is crucial in trigonometry because it allows us to apply trigonometric ratios to find unknown angles or side lengths based on the given information.

Q: How are trigonometric ratios used in the example provided?

In the example, the trigonometric ratio of tangent is used to find the length of BC, which represents the distance between the foot of the ladder and the bottom of the wall.

Q: Can trigonometric ratios other than tangent be used in similar problems?

Yes, trigonometric ratios such as sine or cosine can also be used depending on the given information. In this specific example, tangent was used, but cosine or sine would yield the same result.

Summary & Key Takeaways

  • Trigonometry has practical applications in finding heights and distances in real-life situations.

  • Trigonometric ratios are used to form right triangles and solve problems.

  • In the example given, the distance between the foot of a ladder and the bottom of a wall is found using the trigonometric ratio of tangent.
