Well, given that technic is quantized down to stud or half stud sizes, the
solution may not be obvious.

The easiest angles to create are due to 3-4-5 triangles.  Most of the bent
liftarms are bent based on those angles.

The tri-blade liftarms (available in Gigamesh) give you a nice 120 degree angle,
and can be combined to give you 60 degree angles.

45 degree angles are not so simple.  Do you have a solution in mind?  I know
that one of the bent liftarms supports 45 degree angles, but they can be kind of
gangly.
