\nSolution:
\n\"10th
\n\"Ex<\/p>\n

Ex 6.3 Class 10 Samacheer Question 2.<\/strong>
\nThe horizontal distance between two buildings is 70 m. The angle of depression of the top of the first building when seen from the top of the second building is 45\u00b0. If the height of the second building is 120 m, find the height of the first building.
\nSolution:
\n\"10th
\n\"10th
\n\u2234 The height of the first building is 50m.<\/p>\n

10th Maths 6.3 Question 3.<\/strong>
\nFrom the top of the tower 60 m high the angles of depression of the top and bottom of a vertical lamp post are observed to be 38\u00b0 and 60\u00b0 respectively. Find the height of the lamp post, (tan 38\u00b0 = 0.7813, \\(\\sqrt{3}\\) = 1.732)
\nSolution:
\n\"10th
\nFrom the figure,
\n\"10th
\n\u2234 The height of the lamp post = CE
\nCE = BD = 60 – 27.064 = 32.93 m.<\/p>\n

10th Maths Trigonometry Exercise 6.3 Question 4.<\/strong>
\nAn aeroplane at an altitude of 1800 m finds that two boats are sailing towards it in the same direction. The angles of depression of the boats as observed from the aeroplane are 60\u00b0 and 30\u00b0 respectively. Find the distance between the two boats. (\\(\\sqrt{3}\\) = 1.732)
\nSolution:
\n\"10th
\n\"10th
\nDistance between the boats = 1200\\(\\sqrt{3}\\) m
\n= 2078.4 m<\/p>\n

10th Maths Exercise 6.3 Question 5.<\/strong>
\nFrom the top of a lighthouse, the angle of depression of two ships on the opposite sides of it are observed to be 30\u00b0 and 60\u00b0. If the height of the lighthouse is h meters and the line joining the ships passes through the foot of the lighthouse, show that the distance between the ships is \\(\\frac{4 h}{\\sqrt{3}}\\) m.
\nSolution:
\n\"10th
\nIt is proved.<\/p>\n

10th Maths Exercise 6.4 Samacheer Kalvi Question 6.<\/strong>
\nA lift in a building of height 90 feet with transparent glass walls is descending from the top of the building. At the top of the building, the angle of depression to a fountain in the garden is 60\u00b0. Two minutes later, the angle of depression reduces to 30\u00b0. If the fountain is \\(30 \\sqrt{3}\\) feet from the entrance of the lift, find the speed of the lift which is descending.
