A friend of mine is trying to machine apart.
We have a circle of known diameter. Picture a this circle inside of a 60 degree angle. We need to know how far the tangents are from the corner of the angle.
How would we set this up.
Thanks

Hello, jonb!
sa-ri-ga-ma has the best approach!
We have a circle of known diameter.
Picture this circle inside of a 60° angle.
We need to know how far the tangents are from the corner of the angle.
How would we set this up?Code:/ / * * * /* * * * * * / /* O * / * * * / * * | * / * | / * |r * / * * | * / * 30° * | * * - - - - - - - * * * A B
$\displaystyle \Delta OBA$ is a 30-60-90 right triangle.
We have: .$\displaystyle \angle OAB = 30^o,\;OB = r$
You can now find $\displaystyle AB.$
