Question

the electric pole is 10m heigh.A steel wire field 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:

MARK ME BRAINLIEST.

Given :

OA = 10 m ( electric pole)

∠B = 45°

Let OA be the electric Pole and B be  the point on the ground.

Let BA = x cm

In ∆ABO

sin 45° = AO /AB (perpendicular/ hypotenuse)

1 / √ 2 = 10 / x

x = 10 √2

x = 10 × 1.414    (Given √2 = 1.414)

x = 14.14 m

Hence, length of the wire is 14.14 m.
