Let the angle be ( x = 40^\circ ). The supplementary angle is ( 180^\circ - x = 140^\circ ). According to the problem, ( x ) is 40 degrees less than three times its supplementary angle, which can be expressed as ( x = 3(140) - 40 ). Solving this gives ( x = 420 - 40 = 380 ), which contradicts ( x = 40 ). Therefore, the angle cannot satisfy the given condition.
40 + x = 180 180 - 40 = 140 supplementary angle = 140 degrees
It is 120-degree angle are supplementary.

Let the angle be ( x = 40^\circ ). The supplementary angle is ( 180^\circ - x = 140^\circ ). According to the problem, ( x ) is 40 degrees less than three times its supplementary angle, which can be expressed as ( x = 3(140) - 40 ). Solving this gives ( x = 420 - 40 = 380 ), which contradicts ( x = 40 ). Therefore, the angle cannot satisfy the given condition.
40 + x = 180 180 - 40 = 140 supplementary angle = 140 degrees
Its supplementary angle is 121 degrees
118 degree angle
An angle is supplementary to another if their measures add up to 180 degrees. To find the angle that is supplementary to a 75-degree angle, subtract 75 from 180. Therefore, 180 - 75 = 105 degrees. Thus, the angle that is supplementary to a 75-degree angle is 105 degrees.
83 degree angle
To draw an angle of 40 degrees, use a protractor: place the protractor's midpoint at the angle's vertex, align one side with the zero line, and mark a point at 40 degrees. Draw a line from the vertex through this point to create the 40-degree angle. To copy its supplementary angle, measure 180 degrees from the same vertex using the protractor and mark a new point, then draw a line through the vertex to this point, completing the supplementary angle.
The supplementary angle to a 97-degree angle is calculated by subtracting the angle from 180 degrees. Therefore, the supplementary angle is 180 - 97 = 83 degrees.
