A guy wire is attached to a vertical pole or
height 16 m is 20 m long and has a stake
attached to the other end:
(a) How far from the base of the pole should the stake
be driven so that the wire will be taut ?
(i) 12 m (ii) 14 m
(iii) 15 m (iv) 16m
(b) Which theorem is used in above problem
(i) BPT                                 (ii) Mid point theorem
(iii) Pythagoras theorem  (iv) Angle bisector theorem
c) In the above problem, if the height of pole becomes 14 m, then find how far from
the base of the pole should the stake be driven so that the wire wll be taut?
(i) 3√51m      (ii)2√51m
(iii)4√51m     (iv)5√51m
(d)If ABC Is an isosceles triangle ,right angled at C, then which of the following is
true?
(i) AB² =2AC²             (ii)AC² = 2AB²
(iii)AB² = AC²                   (iv)AB² + AC² = 0
(c) A ladder 10 m long reaches a window 8 m above the ground. What is the distance
of the foot of the ladder from the base of the wall ?
