Help.

Ok, this is a review question, but I don't get how they got the answer:

The measure of one angle is 47 degrees. Find the measure of its supplement.

The answer is 133 degrees.

Supplementary angles are angles that make up 180 degrees or a straight line.....so in this case they subtracted 180 and 47....

In mathematic, supplementary angles mean two angles who's sum is 180. 
Perhaps you may be confused with complementary angles, which means two angles who's sum is 90.
