Answer:
142.4°
Explanation:
- Supplementary angles are angles that add up to 180 degrees.
- Therefore, if two angles a and b are supplementary then;
∠a + ∠b = 180°
In this case, we are given an angle m∠B= 37.6°
We are required to determine the supplement of the angle;
Therefore;
Assuming the supplement of the angle given is m∠A
Then;
m∠A = 180° - 37.6°
= 142.4°
Thus, the supplement of the angle is 142.4°
