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:
See below
Step-by-step explanation:
c = (a^2 + 3b) / 4 multiply both sides by 4
4c = a^2 + 3b subtract a^2 from both sides
4c - a^2 = 3b now divide both sides by 3
(4c-a^2) / 3 = b
