Soumen Maity  (9 years ago)

the sunrays fall on the building in an angle z (say)
So, tan(z)= G/D
Now, for the neighboring building, though it has height C(different than first) yet the angle would be same, because compairing to Sun it is negligible.

So, the original height is, tan(z)= C/x. (say x is the height of the building)
So, the height is DC/G (ans)

as the shadow of the building is 3 feet more than the building just as the height D+ 3=SHADOW =G.similarly the shadow is given C ,hence the height =C-3.hence the height is Z.

amolak singh  (9 years ago)

when the height of building=d
then shadow =g
so the shadow of building=c
then height of building=z.
becoz the height of shadow is the third letter to the height of building.

this problem is related to similar triangle.Let the height of neighbouring building be x. Therefore D/X=G/C. So x=CD/G
