I doubt you have both. What created that image?
And I'm not going to do an image processing example if you have the endpoints in a vector and can do a simple math thing like the answer below (scroll down).

A(a,b) B(c,d) C(e,f)
AB = (c-a,d-b),BC = (e-c,f-d)
cosABC = AB*BC/|AB|*|BC| = (c-a,d-b)*(e-c,f-d)/|(c-a,d-b)|*|(e-c,f-d)|
so , acos(cosABC)*180/pi
