Question

two poles of height 12 metre and 20 metres stand upright on a plane ground if the distance between their feet is 15 find the distance between their tops

please help it is urgent​

Answer 1

Step-by-step explanation:

Let RS be pole of height 10 m and PT be pole of height 15m.

ST is the distance between their feet i.e. 12m.

∴RQ=ST=12 m

And, RS=QT=10m ....[∵□RQTS is a rectangle]

Now, in △PQR,

By Pythagoras theorem,

PR

=PQ

+QR

∴PR

=25+144

PR=13 m.

Hence, the distance between their tops is 13m.
