Question:

Two poles of heights 6 m and 11 m stand on a plane ground. If the distance between the feet of the poles is 12 m, find the distance between their tops.

Solution:

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 AE

Proof : According to Pythagoras theorem,

AE² = AB² + BE²

AE² = 12² + 5² = 169

AE = 13

∴ Distance between the tops of two poles = 13 m
