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

$\angle BOC and \angle BAC$ 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.
