A) \[48\,m\]
B) \[36\,m\]
C) \[54\,m\]
D) \[72\,m\]
Correct Answer: A
Solution :
In \[\Delta DAB,\,\,\tan \theta =\frac{64}{d}\Rightarrow d=64\cot \theta \] ? (1) In \[\Delta DCE,\,\,\tan ({{90}^{o}}-\theta )=\frac{36}{d}\] ? (2) \[\therefore \,\,(1)\times (2)\] \[\Rightarrow 64\times 36={{d}^{2}}\] \[d=48\]You need to login to perform this action.
