In this article i'll tell you that a way to realize height of building , several students they don’t knowledge to search out theheight of building, this let's get begin .
Given Data:
Base distance = x = 2000 ft - Angle = theta = 30°
We have to find Opposite side = Y = ?     Where Y = Height of building
SOLUTION :
We know that :tanθ = Opposite / adjacent  = Y /  X
So  ,  2000 x tan 30°  = Y / 2000 x 2000
NOW ,  2000 X TAN 30°  = Y    So        Y = 2000 ( 0.57 )
Y = Height of Building = 1154 ft
