| **The sum of the vertical angles MOE and DOC, formed at the intersection of straight lines MC and DE, is 140 degrees. Find the angle MOE.**

The vertical angles at the intersection of straight lines are equal, then the angle MOE = DОС.

By condition, the sum of the angles MOE + DOE = 140, then MOE = DOC = 140/2 = 70.

The angle MOD is adjacent to the angle MOE, the sum of which is 180, then the angle MOD = (180 – 70) = 110.

Answer: The angle MOD is 110.
