Ответ:
x = 21
Step-by-step explanation:
Inscribed angle = (3x - 3)°
Intercepted arc measure = 120°
Thus:
(3x - 3)° = ½(120°) => an inscribed angle of any circle = ½ the measure of its intercepted arc.
Multiply both sides by 2
2(3x - 3) = 120
6x - 6 = 120
6x - 6 + 6 = 120 + 6
6x = 126
6x/6 = 126/6
x = 21
