​

Answer 1

answer is 13..

hope it helps if u want the solution then comment on this ....

Answer 2

Answer:

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)2=(AE)2+(AE)2=(12)2+(5)2=144+25=169

⇒AC=13 m

So, the distance between their tops  is 13 m.
