Question

10. A guy wire attached to a vertical pole of height 18 m
is 24 m long and has a stake attached to the other
end. How far from the base of the pole should the
stake be driven so that the wire will be taut?
​

Answer 1

Let AC be the wire and AB be the height of the pole.

AC = 24 cm

AB = 18 cm

According to Pythagoras theorem,

AC2 = AB2+BC2

242 = 182+BC2

576 = 324+BC2

BC2 = 576-324

BC2 = 252

Taking square root on both sides,

BC = √252

= √(4×9×7)

= 2×3√7

= 6√7 cm

Hence the distance is 6√7 cm.
