Ppt On Some Applications Of Trigonometry Class 10 Download These SolutionsYou can download these solutions in PDF from the above link. Find the height of the pole, if the angle made by the rope with the ground level is 30. Solution. A tree breaks due to storm and the broken part bends so that the top of the tree touches the ground making an angle 30 with it. The distance between the foot of the tree to the point where the top touches the ground is 8 m. Ppt On Some Applications Of Trigonometry Class 10 Install Two SlidesA contractor plans to install two slides for the children to play in a park. For the children below the age of 5 years, she prefers to have a slide whose top is at a height of 1.5 m, and is inclined at an angle of 30 to the ground, whereas for elder children, she wants to have a steep slide at a height of 3 m, and inclined at an angle of 60 to the ground. What should be the length of the slide in each case Solution. The angle of elevation of the top of a tower from a point on the ground, which is 30 m away from the foot of the tower is 30. The string attached to the kite is temporarily tied to a point on the ground. Find the length of the string, assuming that there is no slack in the string. The angle of elevation from his eyes to the top of the building increases from 30 to 60 as he walks towards the building. From a point on the ground, the angles of elevation of the bottom and the top of a transmission tower fixed at the top of a 20 m high building are 45 and 60 respectively. 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. The angle of elevation of the top of a building from the foot of a 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. 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 of the top of the poles are 60 and 30 respectively. Find the height of the poles and the distance of the point from the poles. From a point on the other bank 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 joining this point to the foot of the tower, the angle of elevation of the top of the tower is 30 (see the given figure). Find the height of the tower and the width of the CD and 20 m from pole AB. From the top of a 7 m high building, the angle of elevation of the top of a cable tower is 60 and the angle of depression of its foot is 45.
