Question

two poles of height and 13 metre height are placed opposite to each other across a 12 metre long road . find the distance between their tops .​

Answer 1

Answer:

Sol:

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.

same as this

Answer 2

Answer:

In Δ ABC

AC² = AO² + CO²

AC² = 12² + 5²

AC² = 114 + 25

AC² = 169

AC² = 13 m

distance between top of two poles is 13 m....
