Question A Satellite flying at height h is watching the top of the two tallest mountains in Uttarakhand and Karnataka ,them being Nanda Devi(height 7,816m) and Mullayanagiri (height 1,930 m). The angles of depression from the satellite, to the top of Nanda Devi and Mullayanagiri are 30° and 60° respectively. If the distance between the peaks of two mountains is 1937 km , and the satellite is vertically above the midpoint of the distance between the two mountains.Question 1 The distance of the satellite from the top of Nanda Devi is (a) 1139.4 km (b) 577.52 km (c) 1937 km (d) 1025.36 km(a) 1139.4 km Question 2 The distance of the satellite from the top of Mullayanagiri is (a) 1139.4 km (b) 577.52 km (c) 1937 km (d) 1025.36 km(c) 1937 km Question 3 The distance of the satellite from the ground is (a) 1139.4 km (b) 577.52 km (c) 1937 km (d) 1025.36 km(b) 577.52 km Question 4 What is the angle of elevation if a man is standing at a distance of 7816m from Nanda Devi? (a) 30° (b) 45° (c) 60° (d) 0° (b) 45° Question 5 If a mile stone very far away from, makes 45 to the top of Mullanyangiri montain. So, find the distance of this mile stone form the mountain. (a) 1118.327 km (b) 566.976 km (c) 1937 km (d) 1025.36 km(c) 1937 km
