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?

Figure is in the attachment.↑↑
Let AB be the pole and AC be the wire.
In ΔABC, using Pythagoras theorem
BC = 6√7 m
Hence , the distance of the stake from the base of pole is 6√7 m.

Hope this will help you... : )
half ans in the attachment..
hope it hlps uh...
= Let AB be the pole and AC be the wire.
= in ∇ABC usimg pythagoras theram..
= AC² =BB²+BC²
= 24²=82+BC²
= BC²=576- 324
= BC²= 252
