(I'll use degrees as it is more common for household projects, but can easily be changed into radians as needed), As the angle pointed to by the yellow arrow is $\arctan(\frac{1}{3})\approx 18.43^\circ$, that means the red angles are $90^\circ - \arctan(\frac{1}{3})\approx 71.57^\circ$. What is the point of Thrower's Bandolier? A circle's radius is always half the length of its diameter. Neither the arc itself nor its angle is known, but the arc should be equal to $\frac{2\pi r}{x}$. My goal is to find the angle at which the circle passes the 2nd point.
