Class 10 Maths | Applications of Trigonometry | Complete Board Exam Revision in One Go!
Prepare for your Class 10 Maths board exams with this full revision of Chapter 9: Some Applications of Trigonometry in just one session! 📚✏️ We’ll solve important exam-style problems, including: ✔️ Finding the length of a ladder leaning against a pole ✔️ Ratio of heights of two towers ✔️ Lighthouse and ships problem ✔️ Angle of elevation of the sun from a shadow ✔️ Height of a chimney using angle of elevation ✔️ Broken tree problem ✔️ Proving tower height using complementary angles AB is a 6 m high pole and CD is a ladder inclined at an angle of 60° to the horizontal and reaches up to a point D of pole. If AD = 2.54 m. Find the length of the ladder. (Use √3 = 1.73) The tops of two towers of height x and y, standing on level ground, subtend angles of 30° and 60° respectively at the centre of the line joining their feet, then find x : y. The angles of depression of two ships from the top of a light house and on the same side of it are found to be 45° and 30°. If the ships are 200 m apart, find the height of the light house. An observer 1.5m tall is 28.5m away from a chimney. The angle of elevation of the top of the chimney from her eyes is 45o. What is the height of the chimney? If a tower 30 m high, casts a shadow 10√3 m long on the ground, then what is the angle of elevation of the sun? A tree is break due to storm and the broken part bends so that the top of the tree touches the ground making an angle 300 with it. The distance between the foot of the tree to the point where the top touches the ground is 8m. Find the height of the tree. The angle of elevation of the top of a tower from two points distant a and b from its foot are complementary. Prove that the height of the tower is √ab.
