The formula for Chart Convergency (CC) on a Lambert conformal conic chart is:
CC = dlong x sin P of O
Constant of the Cone is sin P of O calculated for you
Straight lines on Lamberts approximate to Great Circles (GC), so you are looking at a GC. If Initial GC is 080 and Final GC is 092 the convergency is the difference between the two = 12 degrees
Going back to your formula for CC
CC = dlong x sin P of O
12 = dlong x 0.8
dlong = 15 degrees
From 004W you end up at 011E
