Answer:
The correct answer is D. 142.4°
Explanation:
Let's recall that supplementary angles are those angles that add up to 180 degrees, while complementary angles are those angles whose sum is 90 degrees.
Therefore,
The supplement of m∠B = 37.6⁰ is:
180 - 37.6 = 142.4°
The correct answer is D. 142.4°
