The correct answer is B. 137, same side exterior angles are supplementary
Explanation:
You see, we know the value of 2 = 43 degrees. That angle is the same angle as 6, which is also 43 degrees. Angles 6 and 8 are on the same line, therefore their sum = 180 degrees. So, angle 8 = 180 - angle 6, which is in this case 137 degrees. The second part: They are on the same side and we see that they are on the exterior, so their sum is also 180, because they are supplementary. Hope this helps!
