As suggested by Sunset Machine you can duplicate the angle by chucking and truing the sample piece in your lathe. Then mount a dial test indicator somewhere on the compound so that the indicator point is contacting the angle at the 9 o'clock position as if it were the cutting tool. By tapping the compound one way or the other you'll eventually be able to achieve a 0,0 reading as you wind the compound in and out. Now you have the angle set even though you haven't measured it.
To accurately measure the depth of the angle you can compare your depth with the sample part depth by using something like a 644 jz Starrett depth indicator with an appropriate contact point. A point that contacts the angle anyplace within its extremities will suffice once the angle is duplicated.
To actually measure the angle is something you may want to do later. For now you can make your parts.
