| Let the value of the central angle AOB be equal to X0, and the value of the inscribed angle ACB equal to Y0.
Then, by hypothesis, X – Y = 82. (1).
Since the value of the inscribed angle is equal to half the value of the central angle, then:
2 * Y = X. (2).
Let us solve the system of two equations 1 and 2 by the substitution method.
2 * Y – Y = 82.
Y = ASB = 82.
X = AOB = Y + 82 = 82 + 82 = 164.
Answer: The center angle is 164, the inscribed angle is 82.
