answer
Let the poles be Pole A and pole B respectively .
Height of pole A = 15 m
Height of pole B = 6 m.
We can easily observe that , height of pole A is greater than the height of pole B .
This is by an extent of 9 m .
Now , the distance between the base of the poles is 8 m .
We need to find the distance between the tops .
Applying Pythagoras theorem here ;
Distance between the tops of the towers = √[ { Distance between bases }² + { difference in height }² ]
=> √ ( 81 + 64 )
=> √ 145 m
