Answer 1

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,

=144+25=169

⇒AC=13 m

So, the distance between their tops is 13 m.

Answer 2

Answer:

184 m

Step-by-step explanation:

distance between 3 poles = 24 m

distance between each pole =24/3=8 m

distance between 1st and last pole = 24×8=192m -8m =184 m
