Question

22. A 1500' zip line is connected between two poles. If the line makes an

18° angle with the ground, how far apart are the poles?

Answer 1

The distance between to poles is 1430' .

Explanation:

You have to use Coeine Rule, cosθ = adjacent/hypotenuse. Then substitute the following values into the formula :

`\cos(θ) = (adj.)/(hypo.)`

Let adj. = d,

Let hypo. = 1500' ,

Let θ = 18°,

`\cos(18) = (d)/(1500)`

`d = 1500 \cos(18)`

`d = 1430 \: (3s.f)`
