Прямые \(\displaystyle CD\) и \(\displaystyle MN\) пересекаются в точке \(\displaystyle O\). Найдите значения углов \(\displaystyle DOM\), \(\displaystyle COM\) и \(\displaystyle CON\), если известно, что \(\displaystyle ∠ DON=30^{\circ}.\)

\(\displaystyle ∠ DOM=\) [ ]\(\displaystyle ^{\circ}\)

\(\displaystyle ∠ COM=\) [ ]\(\displaystyle ^{\circ}\)

\(\displaystyle ∠ CON=\) [ ]\(\displaystyle ^{\circ}\)
