Question

the distance between the tips of the poles 10m and 18m high is 17m then the distance between their foot is​

Answer 1

Answer:

Two poles of heights 10 m and 15 m, stand on a plane ground. If the distance between their feet is 12 m, the distance between their tops is:

Answer 2

Answer:

15 m

Step-by-step explanation:

from the attached figure

in ∆ABC, AB = 8m , AC = 17 m

by Pythagoras theorem,

AB^2 + BC^2 = AC^2

BC = √AC^2 - AB^2

$\sqrt{ {17}^{2} - {8}^{2} } = \sqrt{289 - 64} = \sqrt{225} = 15$

BC = 15 m

since DE is the distance between two poles

DE = BC = 15 m
