Ответ:

углы АМК и АМ смежные, их сумма равна 180° , то угол АМК= 180° - 120°= 60°

Угол АМК=60°, угол АКМ=60°, то угол КАМ=60°( поскольку сумма углов треугольника =180°)

тогда АМ=МК=АК=10 см. Р= 3×АМ=30 см

There are schools of general education, where the pupils study Russian (or a native language), Literature, Mathematics, History, Biology, Geography, Music, Arts, Foreign Languages.
