Answer:
Hello! The answer is 15°.
Explanation:
Supplementary angles add up to 180°.
To find the measure of each angle, we can now set up an equation because we have the total that supplementary angles add up to:
x + 165 = 180
Now, we can subtract 165 from both sides to get x by itself:
x + 165 = 180
-165 -165
This leaves us with:
x = 15
