Step-by-step explanation:
height of tower 1 = 9m
height of tower 2 =14m
distance between their feet = 12m
(refer to the figure above for the diagram)
AC = AD - CD.....(Since BE = CD..Hence CD = 9meters)
AC = 14 - 9
AC = 5 meters
in triangle ABC
by pythagoras theorem
(hypo)2 = (perp)2 + (base)2
(AB)2 = (5)2 + (12)2
AB = 13meters
hence.the distance between their tops is of 13meters
hope it helps❤
