# an electric pole is 12m high . a steel wire is tied to the top of the pole is affixed at a point on the ground to the pole upright . if the wire makes an angle of 600 with the horizontal through the foot of the poles . find the length of the wire.

Dear Student,

We form our diagram from given information , As :

Here ,

Height of pole  = BC  =  12 m  , Length of wire =  AC  =  x  m

We know :  , So

Therefore,

Length of wire  =  13.86 m                                                            ( Ans )

Hope this information will clear your doubts about Some Applications of Trigonometry.

angle =60•
P=12
H=?
P÷H= sin60
12÷H=√3÷2
H=24÷√3
know rationalize it
24÷√3×√3÷√3
=8√3 m

IN TRIANGLE ABC LET AABREPRESENT THE POLE AND AACRREPRESTTHE WIRE WHILE BC BE THE SSISTANCE BBETWEEN THE POLE AND THE POINT AT WHICH THE WIRE IS TIED. sin 60°=root 3/2 AB/AC=root 3/2 12/AC=root 3/2 AC=8root3
