Two poles of height 6 meters and 11 meters stand on a plane ground. If the distance between their feet is 12 meters then find the difference in the distance between their tops:  Choose the correct option.
A) 12m B) 5m C) 13m D) 11m E) 12m
distance between their tops = sqrt( 12^2+(11-6)^2) = sqrt 169=13m   ANSWER:13m
