Question

two poles of height6m and11m stand on a plane ground if distance between there feet is12mfind distance of top

Answer 1

Given: Two poles AD and CE of height 6 m, 11 m respectively. Distance between the feet of two poles (DC) = 12 m AD = BC = 6 m BE = CE - BC = 11- 6 = 5 m To prove : Find AEProof : According to Pythagoras theorem,AE2 = AB2 + BE2 AE2 = 122 + 52 = 169 AE = 13. ∴ Distance between the tops of two poles = 13 m.
