180-71.57=108.43
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
The measure of a supplementary angle is found by subtracting the given angle from 180 degrees. For a 15-degree angle, the supplementary angle is 180 - 15, which equals 165 degrees. Therefore, the measure of the supplementary angle to a 15-degree angle is 165 degrees.
It is 120-degree angle are supplementary.
140o
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.
180-31=149 149 degree angle
An obtuse angle
101
The supplementary angle to a 145 degree angle will be a 35 degree angle because 145 + 35 = 180.
