Question

2. Two poles of height 15 m and 20 m stand on a
plane ground. If the distance between their top
is 13 m, then find the distance between their
feet.​

Answer 1

Answer:

formula =

20+15-13

35-13

22

hence the distance is 22m

Answer:13m

Step-by-step explanation:

Let AB=15m &CD=20m be the two poles lying on a plane ground with separation distance=12 m between them.

Draw a line AE parallel to BC on CD.

Therefore AE=BC=12 m

Now CD=CE+ED=20m

Or,15+ED=20m

Therefore ED=5m

Now in triangle AED,AD^2=AE^2+ED^2

AD^2=12^2+5^2

Therefore AD=√169=13m

This is the required distance between their tops
