The Statue of Unity situated in Gujarat is the world’s largest Statue which stands over a 58 m high base. As part of the project, a student constructed an inclinometer and wishes to find the height of Statue of Unity using it. He noted following observations from two places : Situation - I: The angle of elevation of the top of Statue from Place A which is 80√3 m away from the base of the Statue is found to be 60°. Situation - II: The angle of elevation of the top of Statue from a Place B which is 40 m above the ground is found to be 30° and entire height of the Statue including the base is found to be 240 m. Based on given information, answer the following questions : (i) Represent the Situation —I with the help of a diagram. (ii) Represent the Situation — II with the help of a diagram. (iii) (a) Calculate the height of Statue excluding the base and also find the height including the base with the help of Situation — I. OR (iii) (b) Find the horizontal distance of point B (Situation — II) from the Statue and the value of tan α, where α is the angle of elevation of top of base of the Statue from point B. 2. Anurag purchased a farmhouse which is in the form of a semicircle of diameter 70 m. He divides it into three parts by taking a point P on the semicircle in such a way that ∠PAB = 30° as shown in the following figure, where O is the centre of semicircle. In part I, he planted saplings of Mango tree, in part II, he grew tomatoes and in part III, he grew oranges. Based on given information, answer the following questions. (i) What is the measure of ∠POA ? (ii) Find the length of wire needed to fence entire piece of land. (iii) (a) Find the area of region in which saplings of Mango tree are planted. OR (iii) (b) Find the length of wire needed to fence the region III. 3. In order to organise, Annual Sports Day, a school prepared an eight lane running track with an integrated football field inside the track area as shown below : The length of innermost lane of the track is 400 m and each subsequent lane is 7.6 m longer than the preceding lane. Based on given information, answer the following questions, using concept of Arithmetic Progression. (i) What is the length of the 6th lane ? (ii) How long is the 8th lane than that of 4th lane ? (iii) (a) While practicing for a race, a student took one round each in first six lanes. Find the total distance covered by the student. OR (iii) (b) A student took one round each in lane 4 to lane 8. Find the total distance covered by the student.
