When the elevation of the sun changes from 45^(@) "to " 30^(@) , the shadow of a tower increases by 60 units then the height of the tower is

The shadow of a vertical tower on level ground increases by 10 metres,when the altitude of the sun changes from angle of elevatin 45^(0) to 30^(0). Find the height of the tower, correct to one place of decimal. (Take sqrt(3)=1.73

The shadow of a vertical tower on level ground increases by 10 m when the altitude of the sun changes from 45^(@) to 30^(@) . Find the height of the tower.

If the angle of elevation of the sun changed from 45^(@) to 60^(@) , then the length of the shadow of a pillar decreases by 10 m .The height of the pillar is :

If the angle of elevation of the Sun changes from 30^(@) to 45^(@) , the length of the shadow of a piller decreases by 20 metres .The height of the pillar is

The height of a tower is 50 meter. When the Sun's altitude increases from 30^(@) to 45^(@) , the length of the shadow of the tower is decreased by x meter. Find the approximate value of x in meter.

If the angle of elevation of the sun decreases from 45^(@) to 30^(@) , then the length of the shadow of a pillar increases by 60m . The height of the pillar is

The shadow of a tower is found to be x metre longer, when the angle of elevation of the sun changes from 60^(@) to 45^(@) . If the height of the tower is 5(3+sqrt(3)) m, then what is x equal to ?

The height of a tower is 100 m. When the angle of elevation of the sun changes from 30o to 45o , the shadow of the tower becomes x metres less. The value of x is (a) 100 m (b) 100sqrt(3)m (c) 100(sqrt(3)-1)m (d) (100)/(sqrt(3))m

The length of the shadow of the vertical tower on level ground increases by 10m when the altitude of the sun changes from 45^@ to 30^@ .The height of the tower is: समतल भूमि पर खड़ी मीनार की छाया की लंबाई 10 मीटर तक बढ़ जाती है जब सूर्य की ऊँचाई 45^@ से 30^@ तक बदल जाती है। टॉवर की ऊंचाई है:
