Applying the inscribed angle theorem, the value of x in the circle is: 126°.
What is the Inscribed Angle Theorem?
According to the inscribed angle theorem, the measure of the inscribed angle, 63° is one-half of the measure of central angle, x, as shown in the circle given.
Therefore, we would have the following equation:
1/2(x) = 63
x = 2(63)
x = 126°
