Центральные углы, на сколько я помню, всегда равны 90° и опираются на диаметр. Остальные углы, опирающиеся на дуги, можно найти разделив дугу на 2 (соответсвенно если надо найти дугу, но нужно угол, опирающийся на дугу умножить на два)

Предполагаю, раз дано два угла 60° и 80°, то дуги, на которые они опираются, равны 120° и 160°. Но эти углы не центральные.

Или центральные углы опираются на дугу равную 180°, если сформулировать по другому
