Question

a steel wire tied to the top of an electric pole is a fixed at a point on the ground at a distance of 6 m from the foot of the pole if the wire makes an angle of elevation of 60 degree find the length of the wire​

Answer 1

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.

Answer 2

the length of the wire is 12 cm
