Angle C is an inscribed angle of circle P. Angle C measures (x + 2) degrees and arc AB measures (16x) degrees. Find x

According to the Power of Points theorem, angle C is 1/2 of the degree measure of arc AB. This means that:
x + 2 = 1/2 * (16x)
x + 2 = 8x
7x = 2
x = 2/7
Are you sure these are the dimensions, as usually x is a bigger integer?
