Answer :
Since the measure of an angle is 12 degrees less than the measure of its supplement, then x=180-x-12 or 2x=168 or x=84 and 180-x=96. Step 4. ANSWER: The angle is 84 degrees and its supplementary angle is 96 degrees.
Answer:
168
Step-by-step explanation:
Supplementary angle is two angles that total 180 degrees.
180-12=168
