bird on line

If the combined weight of the bird and rope is W, what is the tension in the rope in terms of θ and W?

Select one:
a. W cosθ / sinθ
b. W tanθ
c. W/(2sinθ)
d. W/(2cosθ)

θ is not defined. It is assumed to be the angle with the horizontal.

By finding resultant of two cables at θ with <i>horizontal</i>.
W=2Tsin(θ)
Solve for T=tension in one of the cables.
