I have one arc with given data :
- centre point
- arc start point angle
- arc end point angle
- arc start point radius
- arc end point radius (both radius are almost same)
now i want to find intersection point of two tangent of this arc. any help please?

If $\alpha$ and $\beta$ are start and end point angles, then the intersection of the two tangents at the endpoints corresponds to an angle of $(\alpha+\beta)/2$ and to a distance from center $d=R/\cos(\beta-\alpha)$, where $R$ is the radius.
