I'm not sure I get the problem right

The arrows superimposed on the lower dial mark the gyro angle for the selected torpedo tube.

But the bearing to the target is read on the top of the line. Draw a line between the centers of the upper and lower dials and the intersection with the two dials will give you the AOB (for the top one) and the bearing (bottom one).

On a dial, read the "relative" value on the inner ring, and the "absolute" value on the outter ring.

See this scan from Norman Friedman's book "Us submarines" through 1945".
