Answer:
x = 122
Explanation:
the measure of the chord- chord angle 125° is half the sum of the arcs intercepted by the angle and its vertical angle, that is
125 =
(x + 6 + x) ← multiply both sides by 2 to clear the fraction
250 = 2x + 6 ( subtract 6 from both sides )
244 = 2x ( divide both sides by 2 )
122 = x
