If O is the ethnocentric of the $$\Delta ABC$$, then


ANSWER

$$\angle BOC and \angle BAC$$ are supplementary


SOLUTION
Suppose a circle is drawn passing through all the vertices of the triangle ABC with centre at O (orthocenter).thus the angle formed at the orhtocenter is the supplement of the angle at the vertex.
$$\angle$$ BAC + $$\angle BOC = 180°$$
So, $$\angle BOC\quad and\quad \angle BAC$$ are supplementary.
Answer (B) $$\angle BOC\quad and\quad \angle BAC$$ are supplementary.

Q5 Subjective Medium
Read the following two statements which are taken as axioms:
(i) If two lines intersect each other, then the vertically opposite angles are not equal.
(ii) If a ray stands on a line, then the sum of two adjacent angles so formed is equal to $$180^0$$.
Is this system of axioms consistent? Justify your answer.
