Welcome to Math Time by Sir Usman! In this video, we solve Class 9 Math Chapter 6 Trigonometry Exercise 6.5 Questions 5, 6 & 7 in detail, covering the step-by-step process to find unknown sides and angles using trigonometric ratios & Pythagoras theorem. This video is designed according to the Punjab Textbook Board syllabus and is perfect for students preparing for Matric exams.

Question 5 deals with a real-life application of trigonometry, finding the width of a canal and the angle PQR in radians. We use Pythagoras theorem and trigonometric ratios to get accurate results.

Question 6 focuses on calculating the length x in a composite figure involving right-angled triangles. This example strengthens your understanding of combining geometry with trigonometry.

Question 7 is about a ladder problem where you find the height of a wall when the distance from the wall and the ladder length are given. This is a classic trigonometry question useful for exams and practical life.

By the end of this video, you will be able to:
✔ Understand and apply sin, cos, tan for problem-solving.
✔ Work with angles in radians and degrees.
✔ Use Pythagoras theorem efficiently in real-world problems.

This lesson is part of our full Chapter 6 Trigonometry series where we cover all exercises with easy explanations and shortcut tips. Watch till the end to avoid common mistakes and score full marks in your exams.
