Correct Answer: 1157625
Correct Answer: 1:3
Explanation:
Let the side of regular hexagon be ?a?
Let height of the tower 1 be h1 and tower 2 be h2
Height of tower 1 = h1 = (distance between A and B)* (tan 30o)= a.1/?3
Distance between A and C = 2*?3.a/2= ?3a
Height of tower 2 = h2 = (distance between A and C)* (tan 45o) = ?3a.1 = ?3a
Ratio of height of towers at B and C respectively =a/?3/?3a = 1/3.
