Question

Two poles of height 10 m and 34 m stand on a playground. If the distance between their feet is
7 m; find the distance between their tops.
​

Answer 1

Step-by-step explanation:

the the difference between their tops will be 7

this is because the angle of elevation is not given but as if we have to find the angle then we will do the following things:

Answer 2

the distance between their tops is 13m.

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

=5

+12

=25+144

PR=13 m.

Hence, the distance between their tops is 13m
