Question

Two poles of height 6and11m stand vertically on a plane ground.If the distance between their feet is 12m;find the distance between their tips

Answer 1

Perpendicular distance between the 2 poles =112
The part of pole above the first =11-6=5
By phythagoros theorem we get rootunder 12²+5²=distance between the poles
Distance between the poles =rootunder 169=13
