Respuesta :
The base of the tower, the guy-wires be secured to the ground will be 73.1 feet.
What are trigonometric identities?
Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
Sinθ = a/b
Where θ = angle to the horizontal, a = Height of the tower, and b = length of the wire.
Also, b = a/sinθ
Given: a = 56 feet, θ = 50°
Substitute these values into equation;
b = 56 /sin 50°
b = 56/0.766
b = 73.1 feet
