You can put this solution on YOUR website! A supplementary angle is the angle that when added to a given angle makes the total 180 degrees.
.
You are given an angle with a measure of 49 degrees. Its supplementary angle must have a measure that when added to 49 degrees gives a total measure of 180 degrees.
.
In equation form this would be:
.
49 + S = 180
.
where S represents the measure of the supplementary angle. To solve this equation subtract 49 degrees from both sides. This eliminates the 49 degrees from the left side and you have:
.
S = 180 - 49
.
Perform the subtraction on the right side and the result is:
.
S = 131 degrees.
.
So the measure of the supplementary angle for 49 degrees is 131 degrees which is the second entry on your list of possible answers.
.
Hope this helps you to understand what a supplementary angle is and how it can be calculated.
