A) 36 m
B) 39 m
C) 15 m
D) 30 m
E) None of these
Correct Answer: B
Solution :
Explanation Option (b) is correct. Let AL, BM be poles with tops at L and M resp. LA = 15m, MB = 30 m, AB = 36 m. Let LN be parallel to the ground LN = AB = 36 m And MN = 30 - 15 = 15 m \[\therefore \,\,\,\,LM=\sqrt{{{36}^{2}}-{{15}^{2}}}\] \[=\sqrt{1296+225}=39\,m.\]You need to login to perform this action.
