Q.15 A straight highway leads to the foot of a tower. A man standing at the top of the tower observes a car at an angle of depression of 30°, which is approaching the foot of the tower with a uniform speed. Six seconds later, the angle of depression of the car is foundto be 60°. Find the time taken by the car to reach the foot of the tower from this point.    • Class 10,Ex 9.1,Question 15, Ncert.SOME AP...   Q.14) A 1.2 m tall girl spots a balloon moving with the wind in a horizontal line at a height of 88.2 m from the ground. The angle of elevation of the balloon from the eyes of the girl at any instant is 60°. After some time, the angle of elevation reduces to 30°.Find the distance travelled by the balloon during the interval.    • Class 10,Ex 9.1,Question 14, Ncert.SOME AP...   Q.13 As observed from the top of a 75 m high lighthouse from the sea-level, the angles ofdepression of two ships are 30° and 45°.

From a point on the otherbank directly opposite the tower, the angle of elevation of the top of the tower is 60°. From another point 20 m away from this point on the line joing this point to the foot of the tower, the angle of elevation of the top of the tower is 30° (see Fig. 9.12). Find the height of the tower and the width of the canal.    • Class 10,Ex 9.1,Question 11, Ncert.SOME AP...   Q10. Two poles of equal heights are standing opposite each other on either side of the road,which is 80 m wide. From a point between them on the road, the angles of elevation ofthe top of the poles are 60° and 30°, respectively. Find the height of the poles and thedistances of the point from the poles.    • Class 10,Ex 9.1,Question 10, Ncert.SOME AP...   Q9. The angle of elevation of the top of a building from the foot of the tower is 30° and the angle of elevation of the top of the tower from the foot of the building is 60°. If the tower is 50 m high, find the height of the building.    • Class 10, Ex 9.1,Question 9, Ncert.SOME AP...   Q8. A statue, 1.6 m tall, stands on the top of a pedestal. From a point on the ground, the angle of elevation of the top of the statue is 60° and from the same point the angle of elevation of the top of the pedestal is 45°. Find the height of the pedestal.    • Class 10, Ex 9.1,Question 8, Ncert.SOME AP...   Q7.
