If you need this angle to make a new gear set, then a simple protractor measurement on left and right tip edge and using a rounded mean value should be enough.

If your plan is to manufacture a missing member, that should mesh with an existing spiral bevel gear, then you should CMM measure a cloud of points on the flanks and therefore create a model of the existing gear, then reverse engineer it with regard to gear cutting tools and tooling available.
