Answer:
The length of the wire is 76.19 m.
Step-by-step explanation:
It is given that a guy wire is attached to the top of a radio antenna and to a point on horizontal ground that 40 m from the base of the antenna.
It means base of the right angled triangle is 40 m.
The wire makes an angle of 58deg 20min with the ground.
1 degree = 60 min
Using this conversion convert the given angle in degree.
In a right angled triangle
Therefore the length of the wire is 76.19 m.
