Angles, an and B are supplementary angles. What is the value of MAngles a and B are supplementary angles. What is the value of M angle a FM angle B equals 43° would the answer be 47° 43° 223° are 137°
If angles A and B are supplementary angles, it means that the sum of their measures is 180 degrees. Therefore, if angle A is 43 degrees, the measure of angle B would be 180 degrees - 43 degrees = 137 degrees.
