Question

The measure of an angle is 176.9°. What is the measure of a supplementary angle?

Answer 1

Here, it is easier to add to 176.9 to get to 180 degrees. First, make it a whole number by adding 0.1, which gives you 177. Then it takes 3 degrees to get to 180, so the answer is 3.1 degrees.

Hope this helps.
