To find the measure of the supplementary angle, we need to know that the sum of the measures of an angle and its supplementary angle is always 180 degrees.
So, to find the measure of the supplementary angle to angle B (which has a measure of 124 degrees), we need to subtract the measure of angle B from 180 degrees.
180 - 124 = 56
Therefore, the measure of the supplementary angle to angle B is 56 degrees.
Supplementary angles are angles that when added are equal to 180 degrees. So to find B's supplementary we do 180 - b
180 - 124 = 56
B's supplementary is 56.
