Question

the height of two poles are 6m and 11m are standing on ground and distance between the two poles are 12m then find the distance between end of the two poles

Answer 1

first join the two ends and than subtract 6 from the 11 hight and than solve see the pic

Answer 2

In triangle ADE,
By Pythagoras Theorem
AD^2=DE^2+AE^3
AD^2=5^2+12^2
AD^2=25+144
AD^2=169
AD=root169
AD=13
So, the distance between the ends of the poles is 13m
