A) \[50\,m\]
B) \[50\,\sqrt{3}\,m\]
C) \[50\,\sqrt{2}\,m\]
D) \[50\,(3-\sqrt{3})\,m\]
Correct Answer: B
Solution :
Let A be the height of tower, \[\tan 45{}^\circ =\frac{PQ}{AQ}=\frac{h}{AQ}\Rightarrow h=AQ\] Where PQ is tower and ABC is the park, with Q being mid point of the side BC and \[PQ=h\] Also, \[A{{Q}^{2}}+B{{Q}^{2}}={{100}^{2}}\]You need to login to perform this action.
