Question

Two poles of 8m and 14m stand upright on a plane ground. If the distance between their tops is 10m.

Find the distance between their feet​

Answer 1

Step-by-step explanation:

Let AB and CD are the poles of heights 15m and 10m such thatAC is 13m.

Now,

CE=BD=10m

CD=BE=10m

∴AE=AB−BE=15−10=5m

Now, in triangle AEC

⇒(13)

=5

+(EC)

2

⇒(EC)

2

=169−25

⇒EC=

144

⇒EC=12

∴BD=12m

Therefore 12m is the distance between the fett of the poles.
