Answer :
Final answer:
The supplementary angle of a 103-degree angle is 77 degrees. This is found by subtracting the given angle from 180 degrees.
Explanation:
The subject of this question is finding the supplementary angle of a given angle. A supplementary angle is the amount of degrees that, when added to the given angle, totals to 180 degrees. In this case, you are asked to find the supplementary angle of a 103-degree angle.
To find the supplementary angle, you should subtract the given angle from 180. Therefore, the steps would be:
Step 1: 180 (the total degrees in a straight line)
Step 2: -103 (the given angle)
Step 3: =77 (the supplementary angle)
Thus, the supplementary angle of a 103-degree angle is 77 degrees.
