If a sun ray's inclination increases from 45^(@) to 60^(@) , the length of the shadow of a tower decreases by 50m. Find the height of the tower (in m).

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

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 :

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

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

If the angle of elevation of sun increases from 0^(@)" to "90^(@) , then the length of shadow of the tower………..

Answer the following by a number or a word or a sentence : The length of the shadow of a 12 m long vertical rod is 8 m. At the same time, the length of the shadow of a tower a 40 m. Find the height of the tower.

If the angle of elevation of sun increases from '0' to 90 then the length of shadow of a tower decreases. Is this true? Justify your answer.

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^(@)
