Пояснення:

по теореме суммы углов треугольника- все углы равны 180°

Пускай углы М,N,K относяться как 3х:4x:5x

3х+4х+5х=180

12х=180

х=15

∠M=3x15=45°

∠N=4x15=60°

∠K=5x15=75°

сумма углов треугольника к равна 180° . сложим все части получим 12, теперь нужно вычислить сколько градусов приходится на один угол. 180:12 = 15. Угол м равен 3*15=45, угол n равен 4*15=60 , угол к равен 5*15=75
