how to do engineer problem?
if the bearing DE is North 08 degree 53 minutes and 56 second west and angle to the right, compute the bearing of FG if angel DEF = 88 deg 12'29'' and EFG=40deg 20'30''

thats tricky
since it is direction NW to pnt E the angle should be subtracted from angle DEF:
88 12 29
-8 53 56
---------
81 6 25 = the angle from true north or 0 deg
now add the angle EFG
81 6 25
40 20 30
======
121 26 55 - is the total angle from north so to describe it for a south east bearing subtract it from 180:
180 00 00
-121 26 55
S 59 34 5 E = bearing FG
check my math
its called problem solviing
