Answer:
1.475
Step-by-step explanation:
It is C because a straight line is 180 degrees, eliminating A. That being said, the “bigger angle” is 12x-30 because it is obtuse. B and D are both acute, while C is obtuse. You can also find the answer by finding x as in the equation 3x+(12x-30)=180. By simplification, x=14. So, plugging it in, 12(14)-30=138.
What is the question asking
Answer:
It is 141°.
Step-by-step explanation:
supplementary angles are angles that sum up to 180°
Therefore; 180-39=141
angle that supplement 39° is 141°.
