If x represents the measure of an angle, then the expression represents the measure of its supplement. hint (90--x) or (360-x)

If x represents the measure of an angle, then the expression (180-x)  represents the measure of its supplement.

Step-by-step explanation:

We know that if two angles are supplement of each other then their sum must be 180 degrees.

Let the other angle be y.

Hence, from the above written definition, we can say that

Subtract x to both sides, we get

Therefore, the expression is (180-x)

If x represents the measure of an angle, then the expression (180-x)  represents the measure of its supplement.
