Question

An electric pole is 10 m high. A steel wire tied to top of the pole is affixed at a point on the ground to keep the pole up right. If the wire makes an angle of 45° with the horizontal through the foot of the pole, find the length of the wire.

Answer 1

Answer:

The length of the wire  is 10√2 m.  

Step-by-step explanation:

GIVEN:

The height of an electric pole , AB = 10 m

Distance between the foot of the ladder and wall  , BC = 2 m  

Angle made by Steel wire , ∠BCA (θ) = 45°

Let AC be the length of the wire (h).

In right angle triangle, ∆ABC ,

sin θ  = P/ H

sin 45° = AB/AC  

1/√2 = 10/h

h = 10 × √2

AB = 10√2 m

Hence , the length of the wire  is 10√2 m.
