Question

An electric pole 15 m high is supported by a wire fixing its one end on the ground at some distance from the pole. If the wire joining the top of the pole is inclined to the ground at an angle of 60°, find the length of the wire.​

Answer 1

• Answer: The length of the wire is 17 meters.

Step-by-step explanation:

Given

length of the pole : 15 m

angle inclined by the wire to the pole from ground :60 deg

let the length of wire : x

therefore

sin (angle) = opposite/hypothesis

sin 60 = 15/x

√3/2 = 15/x

x= 2*15/√3

x = 30/√3

x = 17.320

the length of the wire is :17 m.
