I don't have the multiple-choice options — could you post them?
Without the options, here are some equivalent forms you can use:
- sin(2π/15) = sin(24°)
- sin(2π/15) = sin(13π/15) (since sin(π − x) = sin x)
- sin(2π/15) = cos(π/2 − 2π/15) = cos(11π/30)
If you need the exact value in radicals, I can derive that too — paste the choices or tell me whether you want the radical form.
