The answer is 18
You divide 12 buy -2/3
Step-by-step explanation:
Let the measure of required angle be x degree

Thus, first option is the correct answer.
Answer:
Hey mate, please describe your question perfectly.
When a quadrilateral is inscribed in a circle, the opposite angles are supplementary.
x + 2 + 3x + 6 = 180
4x + 8 = 180
4x = 172
x = 43
Now solve for A
3(43) + 6 = A
129 + 6 = A
135 = A
The measure of angle A is 135 degrees.
Hope this helps =)
