Question 344541: Suppose you were not given the expressions for Angle A and Angle B. Suppose, instead, that both angles are unknown and the only fact you know if that they are supplementary. What expressions would you write for each angle?

Let x = the measure of angle A in degrees. For the measure of angle B we want an expression that will be supplementary with the measure of angle A. In other words we want the expression for the measure of angle A and the expression for the measure of angle B to add up to 180 degrees.

The expression for angle B needs to be something which when added to x makes 180. This expression is: 180-x.

Add x and 180-x and see if you get 180! We don't know x nor do we know 180-x. But we do know that they are supplementary!
