Q. 63.6( 7 Votes )

Two vertical pole

Answer :


AE(height of the first building) = 14 m , CD(height of the second building) = 9 m , ED(distance between their feet) = BC = 12 m


AE – AB = 14 m – 9 m = 5 m


From the figure, ΔABC is a right triangle.


In a right angled triangle


(Hypotenuse) 2 = (Base)2 + (Height)2


where hypotenuse is the longest side.


(AC)2 = (AB)2 + (BC)2


AC2 = (5) 2 + (12) 2


AB2 = 25 + 144 = 169


AB = 13 m
