The complete answer is 122.2608696, or more preferred, 122.2607
I rounded each number to the nearest whole number and added those.
29 + 79 + 42 = 150
If you add the original numbers you would get 149.5, which rounds to 150.
Angle b=180-angleaacb-angle a
angle b=70
More likely because you are doing a job that you enjoy doing.
