To solve supplementary angle word problems, it's essential to understand that supplementary angles sum to 180 degrees. In this case, one angle is defined as 2 degrees less than three times the other angle. This relationship can be expressed with the equations x + y = 180 and y = 3x - 2. By substituting and solving these equations, the measures of the two angles can be determined. Clarity in defining the relationships between the angles is crucial for finding the solution.

Let x and y be the size of the angles.
What does it mean that they are supplementary?
What does it mean that one angle is 2 degrees less than three times the other?
This will give you two equations for the two unknowns x and y.
