A) \[\frac{100}{\sqrt{3}}\,\,\text{m}\]
B) \[100\sqrt{3}\]
C) 86.50 m
D) None of these
Correct Answer: A
Solution :
Here, \[{{\theta }_{1}}=60{}^\circ ,{{\theta }_{2}}=30{}^\circ \] h= 50 m and dc=x \[h=\frac{x}{\cot {{\theta }_{2}}-\cot {{\theta }_{1}}}\] \[\Rightarrow \] \[x=h\,\,(\cot {{\theta }_{2}}-\cot {{\theta }_{1}})\] \[=50\left( \sqrt{30}-\frac{1}{\sqrt{3}} \right)=\frac{50(2)}{\sqrt{3}}\,\text{m}\]You need to login to perform this action.
