Two poles of 10 m and 15 m stand upright on a plane ground. If the distance between the tops is 13 m, find the distance between their feet.
Answer :
Given:
Two poles of 10 m and 15 m
Distance between the tops is 13 m
Formula Used/Theory:-
Pythagoras theorem:-
Base2 + Height2 = Hypotenuse2
Difference between height of poles(Height) = 15m-10m = 5m
Distance between their tops is (Hypotenuse) = 13m
Distance by which poles are separated(Base)
Base2 + Height2 = Hypotenuse2
Base2 + 52 = 132
Base2 + 25 = 169
Base2 = 169-25 = 144
Base = √144 = 12m
Hence; poles are separated by 12m
Result:- poles are separated by 12m
