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