Question 16: A man standing on the line joining the two poles finds that the top of the poles make an angle of elevation of 60ยฐ and 45ยฐ respectively. After walking for sometime towards the other pole, the angles change to 30ยฐ and 60ยฐ respectively. The ratio of the height of the poles is :
Lets say the heights of the poles is h 1 and h2
After moving the angle to the first pole becomes 60 degree and to the second pole becomes 60 degree.
Now by Tan of the given angles, we can find the distances on the ground as indicated in the diagram below.
We see that
h1 + h1โ3 = h1โ3 + โ3 h2
h1 (1-1โ3 ) = h2 โ3 - 1โ3)
h1(โ3โ1)โ3 = h2 ร 2โ3
So, the ratio of the heights is,
โ3โ12
The question is "The ratio of the height of the poles is :"
