Question

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.

Answer 1

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

Answer 2

Oh, ok thank you

Answer 3

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.
