Class 10 CBSE | Case study | 1m tall girl observes the India Gate, find angle of elevation | SQP

In this video, we discuss a class 10 CBSE case study from the chapter Applications of Trigonometry from official CBSE Sample question paper. The question goes like this: India gate (formerly known as All India war memorial) is located near Karthavya path. (formerly Rajpath) at New Delhi. It stands as a memorial to 74187 soldiers of Indian Army, who gave their life in the first world war. This 42m tall structure was designed by Sir Edwin Lutyens in the style of Roman triumphal arches. A student Shreya of height 1 m visited India Gate as a part of her study tour. (i) What is the angle of elevation from Shreya’s eye to the top of India Gate, if she is standing at a distance of 41m away from the India Gate? (ii) If Shreya observes the angle of elevation from her eye to the top of India Gate to be 60o, then how far is the she standing from the base of the India Gate? (iii) A. If the angle of elevation from Shreya’s eye changes from 45° to 30°, when she moves some distance back from the original position. Find the distance she moves back. OR (iii) B. If Shreya moves to a point which is at a distance of 41/√3 m from the India Gate, then find the angle of elevation made by her eye to the top of India Gate. We solve this question by including Shreya's height of 1 m(which cannot be ignored) and drawing suitable diagrams for each question. Since it is a one triangle question, and does not involve hypotenuse we use tan ratio for all of the problems and obtain the necessary values required.
