I would use a protractor, see photo, place the protractor on the edge of the inside of one side of the trailer frame and the other inside edge of the trailer frame should be parallel with the 50 degree line on the protractor.

Another way to verify the angle is to measure the angle where the frame meets the cross member for the trailer bed itself. This angle should measure 65 degrees on each side, which will give you a 50 degree angle for the coupler.

The standard dimension for trailer tongues is 50 degrees so most likely the tongue on your trailer will accept the Atwood A-Frame Undermount Trailer Coupler, item # CA-5335-B.
