Ответ:

OA ≈ 24.24 см.

Пошаговое объяснение:

Расстояние OA можно найти, используя формулу синуса угла:

OA = R × sin(∠A)

Подставим значения:

OA = 28 см × sin(60°)

sin(60°) = sqrt(3)/2, поэтому:

OA = 28 см × sqrt(3)/2

OA = 28 см × 0.866

OA ≈ 24.24 см

Примечание: sqrt( ) – это квадратный корень
