Step-by-step explanation:
2x + 9° + 3x + 1° =180° (opposite angles of a cyclic quadrilateral are supplementary)
5x + 10° = 180°
5x = 180° - 10°
5x = 170°
x = 34°
Now
Angle A
= 2 * 34° + 9°
= 77°

Answer:
answer c for question 9 answer
Expad the expression:
4096x^(6)-18432x^(5)+34560x^(4)-34560x^(3)+19440x^(2)-5832x-729
Green or purple = 10
prob(green or purple) = 10/30 = 1/3
