i got 2 answers ..3 and 5.. :)
62the important thing is that the BASE BC is perpendicular to the line AL where L is the orthocenter
AL is parallel to X axis
so BC will be parallel to Y axis
So both B and C will have the same x coordinae
so B=(t,l) C=(t,m)
centroid is (t+t+1)/3, (l+m+2)/3
it is given in question as 3,1
(2t+1)/3=3
t=4
