The height of a tower is 10 m. What is the length of its shadow when Suns altitude is `45o` ?

The height of a tree is sqrt(3) times the length of its shadow. Find the angle of elevation of the sun

At a particular time , when the sun's altitude is 30^(@) , the length of the shadow of a vertical tower is 45 m . Calculate : (i) the height of the tower , (ii) the length of the shadow of the same tower, when the sun's altitude is : (a) 45^(@) , (b) 60^(@)

The height of a tower is 100 metres. When the angle of elevation of the sun changes from 30^o to 45^o , the shadow of the tower becomes x metres less. The value of x is :

If the ratio of height of a tower and the length of its shadow on the ground is sqrt(3):1 , then the angle of elevation of the sun is…………

The shadow of a tower at a time is three times as long as its shadow when the angle of elevation of the Sun is 60^(@) . Find the angle of elevation of the Sum at the time of the longer shadow.

The height of a tower is 200 m. A model of this tower is made such that the ratio between the height of the actual tower and that of the model is 160:1. Find the height of the model.

The shadow of a tower standing on a level ground is found to be 40m longer when Suns altitude is 30o than when it was 60o . Find the height of the tower.

From the top of a cliff, the angle of depression of the top and bottom of a tower are observed to be 45^(@) and 60^(@) respectively. If the height of the tower is 20 m. Find : (i) the height of the cliff (ii) the distance between the cliff and the tower.

The height of a tower is 132m. A model of this tower is made such that the ratio between the height of the actual tower and that of the model is 120:1. Find the height of the model.

An observer finds that the angular elevation of a tower is theta . On advancing 3m towards the tower, the elevation is 45^(@) and on advancing 2m further more towards the tower, the elevation is 90^(@)-theta . The height of the tower is (assume the height of observer is negligible and observer lies on the same level as the foot of the tower)
