Question

There are 10 in a row . If two are 1/2 m part ,find the distance between the poles at the two ends.​

Answer 1

n poles will have n-1 spaces between them

10 ploes will have:

10 - 1 spaces  

= 9 spaces

The total distance =  distance bewteen two poles x number of spaces

Total distance = 1/2 x 9  

                       = 4.5 m

The distance between the poles at the two ends = 4.5m

Please mark this as brainliest =)

Answer 2

Answer:

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)

=(AE)

+(AE)

=(12)

=144+25=169

⇒AC=13 m

So, the distance between their tops is 13 m.
