Из равенства углов следует, что все углы равны по 60°, так как это ровносторонний треугольник. 2. **Найти ∠АМС.** Поскольку линия MC — биссектриса угла MCD, по условию углы МС и CD равны по 32,5°. **Решение:** - Углы в треугольнике в сумме дают 180°, следовательно ∠АМС = 180° − (двойной угол, отдельно считанный как угол МС) = 180° − 65° = 115°.
