The shadow of a vertical tower on level ground increases by 10 metres, when the altitude of the sun changes from angle of elevatin `45^0to30^0dot` Find the height of the tower, correct to one place of decimal. `(T a k esqrt(3)=1. 73`

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

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.

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 :

The length of shadow of a tower on the plane ground is sqrt(3) times the height of the tower. The angle of elevation of sun is 45^0 (b) 30^0 (c) 60^0 (d) 90^0
