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? Share with your friends Share 0 Shruti Tyagi answered this Dear student, The figure below shows two poles AB and CD such that AB = 10 m and CD = 15 m; And the distance between the top of two poles = BD = 13 mAlso, CE=AB=10 m and DE=DC-CE=15m-10m=5mApplying Pythagoras theorem in rt ∆BED,∴BD2=BE2+DE2⇒132=BE2+52⇒169=BE2+25⇒BE2=169-25=144BE=144=12mBut BE=AC⇒AC=12mThus, the distance between their feet is 12 m Regards 3 View Full Answer Devanshi Bhanderi answered this the distance of the feet is 12m -1
