SAS because If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.
3x + (2x - 25) = 180
5x - 25 = 180
5x - 25 + 25 = 180 + 25
5x = 205
5x / 5 = 205 / 5
X = 41
Hope that is right, sorry if it’s not
Supplementary means it equals 180 degrees
