Q3 of 12 Page 203

Two poles 18m and. 13 m high stand upright in a playground. If their feet are 12 m apart find the distance between their top?


From the given fig;


AD = CB = 13m


So,


DE = 5m.


Also, AB = CD = 12m


Using Pythagoras theorem;


EC2 = ED2 + CD2


EC2 = 52 + 122


EC2 = 25 + 144


EC2 = 169


EC2 = 132


EC = 13 m


So, the distance between the top of the poles is 13 m.
