Answer:
The answer is
104°
Step-by-step explanation:
Let the measure of it's supplement be x
Supplementary angles sum up to 180° which means the sum of 76° and it's supplement is 180°
To find its supplement add 76° and it's supplement and equate it to 180° to find x
So we have
76 + x = 180
x = 180 - 76
We have the final answer as
x = 104°
