The part file has the dimensions needed to answer this question.
The triangles on the sides tell you the width and height of the end. From there
you can calculate the length of the hypotenuse.
h = sqrt(w*w+h*h)
the sin of the angle is height/hypotenuse
from there you take the sin inverse to get the angle.
