Question

two poles 18 m and 13 m high standupright in a playground.if their feet are 12m apart find the distance between their tops

Answer 1

distance between tops are 13m

Answer 2

By the above picture applying the pythagorous theorem we get -
(12)square+(5)square =The distance between the poles squared
So , by the pythagorean triplet of 5,12 and 13, we get the distance between the top of the poles is 13 m
