If your looking for the sum, it would be -5 :)
If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees

Angle 1 and 3 are vertical angles, which mean they are identical. Since angle 3 is given as 111 degrees, then angle 1 is also 111 degrees.
All four angles need to equal 360.
Subtract angle 1 and 3 from 360:
360 - 111 - 111 = 138
Angle 2 and 4 would also be identical, so divide the 138 by 2:
138 / 2 = 69
Angle 2 and angle 4 are both 69 degrees.
