The Total solution for NCERT class 6-12
A guy wire attachedto a vertical pole of height 18 m is 24 m long and has a stake attached to theother end. How far from the base of the pole should the stake be driven so thatthe wire will be taut?
Given, a guy wire attached to a vertical poleof height 18 m is 24 m long and has a stake attached to the other end.
Let AB be the pole and AC be the wire.By Pythagoras theorem,
AC2 = AB2 +BC2242 = 182 + BC2BC2 = 576 – 324BC2 = 252BC = 6√7mTherefore, the distance from the base is 6√7m.
