A 140 degree angle would be called an obtuse angle.
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.
140 degrees
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.
An Obtuse angle is any angle in which its degree is greater than 90 and less than 180.
A 140 degree angle would be called an obtuse angle.

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.
700
The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
