It is known that the sum of adjacent angles is 180 °, which means that in order to find the value of the angle adjacent to the angle ABC given to us, it is necessary to subtract this value of the angle ABC from 180 °:
180 ° -30 ° = 150 ° is the value of the angle adjacent to the given angle ABC;
It is known that the vertical angles are equal, therefore the value of the angle vertical with the angle ABC will be equal to 30 °.
