Question

The tops of two poles of heights 20 m and 14 m are connected by a wire. If the wire makes an angle of 30° with the horizontal, then the length of the wire is ____________.

Options

• 8 m

• 10 m

• 12 m

• 14 m

Answer 1

The tops of two poles of heights 20 m and 14 m are connected by a wire. If the wire makes an angle of 30° with the horizontal, then the length of the wire is 12 m.

Explanation:

`"AE"/"AC" = "sin"  30^circ`

`=> 6/"AC" = 1/2`

`=> "AC" = 12  "m"`
