A) \[57.7\,m\]
B) \[100\sqrt{3}\,m\]
C) \[5.77\,m\]
D) \[\frac{100}{3}\,m\]
Correct Answer: A
Solution :
Let AB be the height of the building (x m), BC be the distance of the observer from the foot of the building and the angle of elevation is\[{{6}^{x}}={{(2\times 3)}^{x}}={{2}^{x}}\times {{3}^{x}}\]. Then \[\Rightarrow \] \[{{6}^{x}}\] \[\therefore \] \[{{6}^{x}}\]You need to login to perform this action.
