Q) A kite is flying at a height of 60 m above the ground level. Ravi, standing at the roof of the house is holding the string straight and observes the angle of elevation of kite as 30Â 0 . From the bottom of the same building, the angle of elevation of kite is 45 0.
Q) The angle of elevation of the top of a building from a point A, on the ground, is 30 deg On moving a distance of 24 m towards its base to the point B, the angle of elevation changes to 60 deg. Find the height of the building and distance of point A from
Q) A tower stands vertically on the ground. A man standing at the top of the tower observes his friend at an angle of depression of 30 deg who is approaching the foot of the tower with a uniform speed. 30 seconds later, the angle of depression changes to 60 deg. Find the time taken
Q) Tejas is standing at the top of a building and observes a car at an angle of depression of 30° as it approaches the base of the building at a uniform speed. 6 seconds later, the angle of depression increases to 60°, and at that moment, the car is 25 m away from the
Q)Â Radio towers are used for transmitting a range of communication services. including radio and television. The tower will either act as an antenna itself or support one or more antennas on its structure. On a similar concept, a radio station tower was built in two sections ‘A’ and ‘B’. Tower is supported by wires from
Q) An electric pole is 10 m high. A steel wire tied to top of the pole is affixed at a point on the ground to keep the pole upright. If the wire makes an angle of 45° with the horizontal through the foot of the pole, find the length of the wire. [Use √2
