Assuming 140' is meant to be 140 minutes of arc then 140' = 140/60 = 21/3 degrees = 2 degrees and 20 minutes.
A 140 degree angle would be called an obtuse angle.
140 degrees is an obtuse angleAn angle of 140 degrees would be called obtuse.
No angle can be complementary to a 140 degree angle, as the sum of complementary angles is 90 degrees. But angles which are supplementary to each other add together to form a 180 degree angle.

40 degrees ( 180 - 140 = 40 )
An angle that equals 140 degrees would be considered an "obtuse" angle. This is because it is greater than 90 degrees but does not exceed a straight line of 180 degrees.
An angle of 140 degrees is an obtuse angle because it is greater than 90 but less than 180 degrees.

The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
