Question

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

Answer 1

Step-by-step explanation:

Given: Two poles AB=11 m and CD=6m

Distance between both poles BD=12 m

Then, create a line segment CE parallel to line BD

So, AE=AB−CD=11−5=6 m

In right angled △AEC,

⇒AC=13 m

So, the distance between their tops is 13 m.
