Applications of Heights and Distances
The video explains an example based on the Applications of Heights and Distances.
- The angle of elevation of a bird from a point 50 m above the lake is 30(Degree) and the angle of depression of its reflection in the lake is 60(Degree). find the height of the bird above the lake. With the diagram
- can u ppls explain heights and distNces
- From the top of a cliff, 50m high, the angle of depression of a buoy is 30 degree . Calculate to the nearest meter , the distance of the buoy from the foot of the cliff
-
Can anyone please answer question c
- The upperpart of tree broken by the wind makes an angle of 45 with the ground and distance from the root to point where the top of the tree touches the ground is 15 m what was the ht of the tree before it was broken
- Two people standing on the same side of a tower in a straight line with it, measure the angles of elevation of the top of the tower as 25° and 50° respectively. If the height of the tower is 70 m, find the distance between the two people.
- from the top of a hill the angle of depression of two consecutive kilometre stones due east are found to be 30 degrees ahd 45 degrees respectively. find the distance of the two stones from the foot of the hill.
- an aeroplane at an altitude of 250m observes the angle of depression of two boats on opposite banks of a river to be 45 degree and 60 degree respectively find width of river(please include diagram and explaination to each step)
- a man on the bank of a stream observes a tree on the opposite bank exactly across the stream he finds the angle of elevation of the top of the tree to be 45. on receding perpendicularly a distance of 4m from the bank, he finds that the angle of elevation reduces by 15 .is this information sufficient for the man to determine the height of the tree and the width of the stream? if so, find them. heights and distance
- The shadow of a tower standing on a level ground is found to be 61.59m longer. When the sun altitudes 34°30`then when it is 50°.find the height of the tower.
