2 would equal to 41 because since its a straight line you would do 180-139 and get 41. Have a good day and ask questions!! :)

A straight line is 180 degrees. So, since the line bisects (or splits the straight line in 2) angle 1 and angle 2 add up to equal 180 degrees.
So, to find angle 2, subtract 139 degrees from 180 to get the second angle, which would be 41 degrees
