Question

1. Two electric poles are crected on the ground. The heights of the poles are 20 m
and 28 m respectively. The distance between the poles is 15 m. To you the top of
the poles, how much wires will be required?

Answer 1

Answer:

17 metres

Step-by-step explanation:

I assume that you mean,

Length(pole1)=20m

Length(pole2)=28m

Perpendicular Distance=10m

Distance b/w tops=x

To solve this, we can use Pythagoras theorem. {c^2=a^2+b^2}

x=√(Difference of heights)^2+(Perpendicular distance)^2)

Difference of heights=28-20=8

x=√(8^2+15^2)

x=√(64+225)

x=√289

x=17m
