Trigonometry in the form of triangulation …

Trigonometry in the form of triangulation forms the basis of navigation, whether it is by land, sea or air. GPS a radio navigation system helps to locate our position on earth with the help of satellites. A guard, stationed at the top of a 240 m tower, observed an unidentified boat coming towards it. A clinometer or inclinometer is an instrument used for measuring angles or slopes(tilt). The guard used the clinometer to measure the angle of depression of the boat coming towards the lighthouse and found it to be 30°.  (Lighthouse of Mumbai Harbour. Picture credits - Times of India Travel) Make a labelled figure on the basis of the given information and calculate the distance of the boat from the foot of the observation tower. 2 After 10 minutes, the guard observed that the boat was approaching the tower and its distance from tower is reduced by 240( - 1) m. He immediately raised the alarm. What was the new angle of depression of the boat from the top of the observation tower? 2 Push-ups are a fast and effective exercise for building strength. These are helpful in almost all sports including athletics. While the push-up primarily targets the muscles of the chest, arms, and shoulders, support required from other muscles helps in toning up the whole body.
