the angle of elevation of a cloud from a point 50m above the lake is 30degree and the angle of depression of its reflection in the lake is 60degree. find the height of the cloud.

• ans-100
  let total height be h.
  tan 30=(h-50)/x
  tan 60=50/x,where x is the horizontal distance b/w cloud and the point of the angle of elevation.
  by solving, h=100

• Ans: 200/3
  let height be h
  tan60=50/x
  so, x=50/sqrt(3)
  Now, tan30=(h-50)/x
  substitute x=50/sqrt(3), we get h=200/3

• ans-25
  let height from 50m above lake to cloud be h.
  tan30=h/base
  tan60=h+50/base
  by solving,h=25m
